Problems with digiKam 5.1.0

[Elle Stone]

Hi All,

I'm running Gentoo Linux and digiKam 5.1.0. I'm having some issues with 
digiKam. Here's the digiKam 5 install information from "About":

Version 5.1.0
Using:
KDE Frameworks 5.23.0
Qt 5.6.1 (built against 5.6.1)
The xcb windowing system

Here are the issues so far:

A. Despite perhaps 6 hours of steady searching and trialing, I haven't 
persuaded digiKam to show a proper icon in my IceWm system tray. All I 
see is a red X. I did manage to get dolphin, konsole, kruler, and kcalc 
to finally have proper icons (before my marathon search session they all 
had the same "red X" icon), so the search was not in vain. But I'd 
really like to have a proper icon for digiKam. I don't care which icon 
from which theme it is, as long as it's not the red X.

B. I deleted a tag labelled "People". I don't have such a tag in my tag 
tree. It reappeared upon starting digiKam. Tried again, same result.

C. I don't use Album categories. I deleted all the album categories and 
they reappeared when I restarted digiKam. Tried again, same result.

D. This is the really serious issue: This morning I spend a couple of 
hours rearranging the tag tree, which was considerably in disarray. Then 
I closed and restarted digiKam. A tag tree that I had moved to a new 
location was back at it's original location. Tried again, same result - 
it just won't stay put.


Here's what I want digiKam to do:

Step 1. Upon adding new files to the database, read the image files 
*once* to get the tags. And then *never* read the image files again.

Step 2. Normally only write to the database. Never write to the image 
files and also don't write to XMP sidecar files.

Step 3. Once I've got the tag tree back to where I'd like it to be, I 
want to write all the tags out to XMP sidecar files. Then I'll use 
exiftool to rewrite selected tags (tagslist, hierarchicalsubject, and a 
few other) back to the image files. Then I'll probably delete the 
existing digikam database and and XMP files, and start over with a clean 
database, hopefully with all the tags properly read in as per step 1 above.

How do I set digiKam up to do the above? Is this even possible? Because 
of D above, it would seem to require not shutting digiKam down until 
I've completely redone the tag tree?

Before starting digiKam 5 I removed all the old digiKam/showFoto 
settings files. Upon starting digiKam 5 I made a new sqlite database, 
and for some reason the database name is "digikam4db" - why is this?

Best,
and thanking you in advance for any help,
Elle
