FWIW, it's not a big surprise that dolphin exhibits the same issues, as
the konqueror file-manager mode now uses the dolphin kpart, which is
apparently what's unstable for you, so switching from konqueror to dolphin
didn't remove the unstable component from your test.
What about gwenview? It can act as a file manager, especially for media
files, and I /believe/ it uses a different component, tho I'm not sure of
that. You can also consider installing krusader (which I've read about
but don't use personally), tho I'm not sure if it uses the same dolphin
file-management kpart or not -- it's likely it does.
FWIW (2), I've not experienced any such unstability here on Gentoo, since
quite earlier in the kde4 cycle (4.2 or 4.3 era, maybe). I AM seeing
issues with thumbnail generation on video files, which seems hit or miss,
but not on still jpeg or other image formats, or on text/pdf/html/fonts/
But FWIW (3), my file management usage tends to split between two types of
tasks, "admin-type" tasks, editing config files, moving files/directories
around, backup, etc, and "user-type" tasks, managing/viewing videos,
For admin-type tasks the thumbnails don't matter to me a lot and I prefer
the traditional semi-gui commander-type interface of mc (midnight
commander), running either at a VT (virtual terminal) outside of X/KDE
entirely, or in a konsole window. This works best for admin-type tasks
since the app and its UI are the same whether I'm in X/KDE or not, I
/don't/ need the thumbnails, etc, and loading them only takes extra time,
and it's quite conceivable that one such admin-type task would be editing
xorg or kde config files themselves, to get them working again when
they're broken and I can't even start X/KDE, so using a tool that doesn't
depend on X/KDE in the first place to do admin tasks like editing their
files is a good idea.
It's only for user-type tasks that the thumbnails are actually useful, as
they let me see the contents of the media files I'm working with. As
such, it's these user-type tasks that I tend to use KDE's tools to work
with, and in fact, gwenview is very useful here -- more useful than
As a result, I don't actually tend to use dolphin, etc, that much, tho it
does remain the configured kde file-management tool and thus pops up when
I click on a directory in a folderview on the desktop, or the like, and
I'll use it for "trivial" tasks. But never-the-less, it's quite stable,
You might try running dolphin from a konsole window. It'll then output a
*LOT* of debugging info to the konsole as it does its thing. Do
understand that even on "normal" installations, it's going to spit out a
lot of very scary looking warnings, etc, that are normal. (Actually, it's
possible I'm getting even more than normal ATM, since I'm in the middle of
the 4.5.3 -> 4.5.4 upgrade and that may be causing some additional
warnings since it's half-and-half, but the point stands, dolphin remains
functional even with all of them.) If/when it crashes, you'll want to
note the last warnings, perhaps comparing them with earlier ones and
eliminating the "normal" ones, and can maybe then use that for debugging.
Similarly, I know I was getting some sort of library mis-match error on
the thumbnailer recently, apparently because I'd upgraded one component
and not the rest and hadn't run the revdep-rebuilder that would normally
correct the issue. This is a somewhat routine issue on Gentoo if you
don't complete the necessary library dependency rebuilds after an upgrade,
so no big deal. I suspect that had a lot to do with the problems I was
having with video-thumbnail generation, but I'm hoping/expecting the
current upgrade to 4.5.4, and subsequent run of the revdep-rebuilder, will
fix that issue. While the binary distributions try to avoid this issue by
building everything against a common reference and then not upgrading it
incompatibly, or upgrading everything else built against it when they do
(the reason you need to get packages for your specific binary distribution
version, a package for a different version or a different distribution
might break), sometimes an ABI dependency gets overlooked and stuff
breaks. It's possible that's what both you and I are seeing, with the
broken thumbnailing, me because I didn't properly complete the revdep-
rebuilds, you because of an overlooked ABI dependency issue.
