Whats the best place to report this issue? 

I usually keep
raw files separately but some are still inside my images tree, so to be
on the safe side I will clean them all out when I have some more time.

fix is to change the first category at the beginning of the index.xml to
Schlüsselbegriffe that is used at the end grpuings. Somehow the Category
name got corrupted.

This index.xml is quite old. I have no idea how this
mismatch happend. Schlüsselbegriffe (key terms) was there from the
beginning and I never modified the file manually. The group definition
at the end of the file uses "Schlüsselbegriffe" but everywhere else
"Schl_.FFFFFFFCsselbegriffe" is used. I guess the program part which
handles the groups ignores the logic for special characters used
elsewhere. The current version of KPA does not create a category
'Schlüsselbegriffe' by default. Instead it creates 'Ereignisse'
(events). 

To be able to open index.xml I renamed everything to
"Schlüsselbegriffe". When I closed KPA I was asked if I wanted to save
it, I confirmed and guess what happend: It crashed again when I tried to
reopen it. When I looked at the file with an editor I noticed that
Schlüsselbegriffe was renamed back to <Category
name="Schl_.FFFFFFFCsselbegriffe"> and the group definition was
untouched <member-groups><member category="Schlüsselbegriffe" ... 

So
there is indeed a bug with the current version and special characters in
category names when groups are used. 

Then I tried it the other way
around: Rename everything to "Schl_.FFFFFFFCsselbegriffe". But then I'm
not able to open KPA, it crashes immediately. OK, until this is fixed I
will avoid umlauts in category names. For now I've renamed
Schlüsselbegriffe to Schluesselbegriffe... 

But something is still
wrong even when /usr/share/icons/oxygen/8x8/emblems/file-broken.png
exists, KPA is still very slow opening the detail view and switching
between pictures and also going back to Home. Maybe it's looking for
different icons besides file-broken.png? Or I need to use a different
folder than the one mentioned above? 

Manually fixing the index.xml and
creating a file-broken.png - or finding a proper icon for it should
hopefully get KPA working for Manfred. (Provided there are no more
images that would cause a crash.)

Hopefully I will get KPA working again. :-)
