Crash appear in Qt. It's abnormal. Sound like something is broken in your
computer. I use 0.10.0 everyday and i cannot reproduce this problem here...

Perhaps it's a package build problem

I use Qt 4.4.3 from the OpenSUSE build service, for OpenSUSE 11.0, with the
following last changelog entries:

* Tue Oct 07 2008 [hidden email]
- fix crashes in QGraphicsProxyWidget dtor

* Mon Sep 29 2008 [hidden email]
- update to 4.4.3:
  * branding && copyright update
  * no code changes

For comparing, what is the distribution and Qt version you work with?

Mandriva 2009.0 with Qt 4.4.3 and KDE 4.1.2

As developper, I compile myself digiKam of course...

This is strange, obviously almost the same.
I would like to compile it by myself, too, but I'm behind a proxy and cannot
access the anonsvn.kde.org in none of the possible ways. Thus, I rely on the
OpenSUSE RPMs.
Alright, I will watch this for a while, and may be repeat this test with Qt
debug symbols installed to get the rest of the hidden backtrace.
Thanks for now

Gilles,

this seems to be the same error I described to you and Marcel via mail. It is
exactly the same BT, so this must be related to the thumbbar generating issue.

Gilles, Rene,

do you run digikam from within a real KDE4 desktop session or from KDE3?
At least on my machine the problem seems to be gone when not starting digiKam
0.10 in KDE3...

Both, under MAndriva 2008.1 (KDE3) and Mandriva 2009.0 (KDE4)

No problem with KDE4 desktop.

With KDE3, you need to set up env variable before to run digiKam. under
Mandriva 2008.1, i use mandriva script name k4 like this :

# k4 digikam
or
# k4 showfoto

... and all work fine

Reverting comment #7, it also crashes in a pure KDE4 session.

René,

are you able to reproduce this error with the latest SVN? Current commits might
have solved the problem, right now I'm not able to reproduce it anymore.

The backtrace for the new crash

I recompiled the RPM source package and reinstalled Digikam. Furthermore I
installed the debug symbols of Digikam.
The crash still happens, even on not selecting different albums before in album
view. Now the backtrace is more detailed. Couldn't you give me a hint? All KDE
applications use Qt, I wonder why does only Digikam crash in that way.

The complete backtrace with kipiplugins debug symbols

I got an even more detailed backtrace of the crash, this time with kipiplugin
debug symbols installed. I think it should now be clear where the crash occurs.

This is fixed in current implementation of kipi-plugins from svn. the problem
