It appears that I have (48x48) icon-view set by default. I have only the
name shown, but dolphin has the preview/detail pane on the right. I set
detail-view if I want dates, etc, or switch to mc (which I have setup as
the top priority open-with option for directories, but embedded set to
use the internal viewer so I can browse in kde apps when I want to,
without it constantly switching me to mc).
But it could be doing it when inspecting the file to see what icon to
use. You're right about that.

=:^) For awhile, back on MS so over a decade ago, IIRC, I had animated
cursors set for everything, including one of the background-busy cursors
with a pointer, set as the default.
So bouncing cursors don't bother me much. But if it gets stuck on a
cursor without a pointer, as in the full-busy cursor, THAT BITES!

Yeah. That's one of the down-sides of ps2 ports. But everybody I know
rather ignores it (few even know it's not in the spec) and treats them as
hotplug anyway, in the spec or not.
Meanwhile, USB is DEFINITELY hotplug speced, but now that you mention it,
I'm using some cheap dollar-store USB extension cables here, without a
lot of shielding, and have some problems with electro-static pulses due
to that. I have a wireless combined-receiver (Logitech) for both
keyboard and mouse, but it's primarily the mouse that's affected. The
ESP triggers a right-mouse-click most frequently, which can be annoying
but usually just pops up a context menu, so nothing major. But
occasionally, it triggers a full mouse reset, which with some xinput/
evdev-driver versions, would often return me to unaccelerated mouse.
That was frustrating on a dual 1920x1080 stacked for 1920x2160 desktop,
but I quickly setup a hotkey to invoke an xset mouse to fix it.
However, on a number of occasions the ESP has been bad enough that I had
to unplug/replug the USB keyboard/mouse receiver, and in one case, it was
apparently bad enough to cause the hardware to kill that USB port
entirely, until I rebooted. Fortunately I have others, tho the one I
switched to is on an addon card, so didn't work in grub when I rebooted.
For some reason I was trying to do something other than default with grub
at the time (IIRC I was testing a git kernel that had issues, and it was
at the primary position, so I had to fallback to an older kernel
manually, to boot properly), and that threw me for a bit, until I
remembered that I had plugged the keyboard/mouse into a different USB
port and replugged it into a built-in port, so grub could detect and
respond to it.

Yeah. It just frustrates me when I have an untraced bug, and even when
simply rebooting (or logging out and back into kde) will fix it, at least
temporarily, I prefer to do some diagnostics and see exactly what's going
on. (With the above, I /know/ it's ESP issues due to the dollar-store
cheap unshielded or close to it USB cables, which is tracked enough for
me. If it gets bad enough, I can simply plug directly, without the
extensions, or quit being so miserly and get properly shielded

Total conjecture here:
Looks like it has the (32-bit proprietary) pdf reader plugin loaded,
presumably for a pdf, and then libreoffice, possibly for the flash.
That does look to be association related, but not the web page but the
flash association. So I was part right and part wrong. I still say
check your associations, tho. But others than the ones I said first.
Meanwhile, since I don't do proprietary here, there's little reason to
have 32-bit at all (except for the 32-bit chroot that does the netbook
builds, but it's not even mounted under normal use, only when I'm
maintaining my 32-bit netbook image), so I run a no-multilib profile,
which simplifies things dramatically. =:^)
I don't have any plugins loaded in firefox at all. I download pdfs to a
temp-working folder open in a folderview on my desktop, and open them
from there, in okular. Flash is a bit of an issue, one I generally
ignore, but for youtube and the like I try to keep one or another
downloader working, then play it in smplayer/vlc/whatever. That's a
hassle, but does mean I already have the files locally if I decide
they're worth saving. And of course I avoid problems of any sort
(including the rash of vulns they've had) with Adobe servantware, but
also the convenience of having them installed, since I won't install it
at all, nor do I believe I could do so legally even if I wanted to, since
I can't agree to the damage waivers, etc, for blackbox software I'm
unable to inspect -- no meeting of the minds there, so those bits of the
EULAs should be illegal because the user can't fairly inspect (or have
someone he trusts inspect, for those who don't read source code) what
he's agreeing to accept responsibility for, but whatever. That's just
me. Others do what they want on their own computers.

Yeah, that's not going to do much (unless it was simply corrupted,

Be aware that migrating is a pain, in part because the migration scripts
are a bit old and at least here, needed some hacking in ordered to work.
And I transferred the filters manually. But it was definitely worth it
for me. And I should be able to save you some time and trouble if you
decide to try it.
You'll need to look at how it handles IMAP, tho. Since I don't use it I
wasn't worried about that. If it works with IMAP at all, that's likely
to vastly simplify your migration, but I don't know if it does. That's
definitely something you'll need to look at on your own, if you do decide
to consider it.

I expect it will. It just became way too much for me. As I said (I
think in this thread) like an aircraft carrier, when all I needed was a
rowboat and a trolling motor. The switch was definitely the right thing
for me. For others, as they say, YMMV. But I do expect akonadi will be
a net benefit for the kdepim stuff over time. Just not for me, as I did
the right thing for me and switched to something else.

That's very much one of the potential positives that should count toward

<The light dawns.> That makes quite some sense, when you put it that
way. I wasn't thinking of same-language captioning. However, now that I
am,I too have noted how effective close-captioning is on various TV
programs in public, restaurants, etc, where it means the sound can be
turned down. The same would certainly apply here.
Then too, while I'm native English-only, I've been exposed to enough
accents and the like that I understand it in contexts that other native-
English speakers have trouble with. The first time I really became aware
of this was back in high school (80s, Colorado, central-US rocky-mountain-
west). The (private, church-based) school rented and showed Chariots of
Fire in the gym one Saturday nite (yes, rather sheltered upbringing in
that regard). Given my time growing up in Kenya, I understood (and
thoroughly enjoyed, I REALLY enjoy hearing different accents!) the
European accents, etc, even in the "non-ideal" acoustics of the gym, with
a the background noise of decent sized crowd of people.
Only afterward, from the comments of others, did I realize my experience
wasn't the norm for the evening. Many of those rocky-mountain-western-US
natives would likely have understood only with difficulty the accents in
the film even under ideal acoustic conditions, let alone the rather noisy
and echo-y acoustics of a gym with a crowd of people and a less-than-
ideal PA system.
They certainly could have used some captioning/subtitles, even tho the
film was nominally in English. Based on that experience, I can certainly
understand the difficulties you may have as a non-native English speaker,
as well, and therefore the positive role English subtitles on English
sound-track media may still play, not just for you, but for so many
others, native English speakers or not, as well.

I've read the same observations in the context of fansubs vs. the
official translations for Japanese anime, among other things. The
official translations may "do the job", but are largely characterized as
not just "silly", but often as "flat" or "dead", without the depth of
meaning and in-side references that they fan-subs often convey far more
successfully, because for them it's an effort of love, not just a job.
And that's when the translations are technically correct, never mind when
they're not, as with silicon/silicone, etc.
If only time wasn't of the nature it is, perhaps I'd have time to get
into all these things of interest, that I've simply had to prioritize out
of my limited scope of /pursued/ interests. =:^\

Indeed. That's one of the nice "extras" I had no idea about when I
switched, but which have very quickly been growing on me. Certainly it's
nothing that can't be done without, but it's a very nice feature to have,
none-the-less. The thing is, I keep finding such things, which is why,
as I said, claws-mail is very quickly growing on me.
BTW, one thing to consider since you mentioned nepomuk for indexing, is
that since mh-format message-stores such as claws-mail uses are simply
plain text files, one per message, if you keep nepomuk (I didn't, as I
don't use that functionality) and let strigi index those files, you'll
have the same sort of fully indexed content as you would have with the
similar maildir format that kmail2 uses and that was one of kmail1's
So you'll have the same indexed search ability on the raw content, you'll
just not have it as integrated with the rest of kde as you will with
kmail. Instead, it'd be indexed (I believe) as would any other more or
less generic text file.

I wonder if that's related to the duplicate message-id bug (the pick one,
right, left, both, dialog). Did that get fixed for 4.7? If not, and the
bug happened with this mail, perhaps you picked "the wrong one", in terms
of proper threading? (It just as easily could have nothing to do with
it, since I'm effectively clueless at to what was causing that bug in the
first place. But it was worry about just this sort of effect that was
one of the factors in my decision that I'd simply had enough, and it was
time to try something without all this needless complication. FWIW,
that's /exactly/ why I dropped the LVM layer I had been experimenting
with on my system, too. I realized the complication level was simply
well above what I could understand to a comfort level necessary for
troubleshooting should something go wrong, and that as such, I'd be
VASTLY better off in a recovery situation if I just killed that to-me
unnecessarily complicating layer in the first place. Akonadi was much
the same, except that it was just my mail at risk, not all the data I had
stored on the affected logical volumes. The point being, there's
complication that provides measurable benefits, and there's needless
complication where the benefits simply don't outweigh the hassle and risk
factor cost of the complications in the first place. For my usage, both
LVM and akonadi fall very much on the wrong side of the cost/benefit
analysis, and are thus very much a WRONG solution for me, however much
they might be a GOOD solution for someone else who weighs the cost/
benefit factors differently due to their different needs.)

Practical problem prioritizing. Cool! =:^)
Just keep that reset script trick on file in case you need it sometime.
As I mentioned above, I use a variation on the theme for my mouse accel
reset, too, and I've used the same basic trick in various other
situations. The trick is thus useful in enough situations that you'll
probably find it useful somewhere, eventually.
Not that it's at all unique or unusual. I expect every sysadmin
eventually has this sort of thing in his bag of tricks. Perhaps you
already do and I'm making a big deal of nothing, but if not, it's worth
putting there, as you'll almost certainly find it useful, eventually.
