Version:           0.10.0-beta7 (using KDE 4.1.3)
OS:                Linux
Installed from:    SuSE RPMs

Just start digikam. Execute Tools->Scan for new images once. When exiting digikam, it crashes. This is not reproducable, happens about every third or fourth time.

Comment 1 Marcel Wiesweg 2008-12-30 21:22:59 UTC

SVN commit 903550 by mwiesweg:

Move some shutdown code from AlbumManager destructor to a cleanUp method that is
called before KApplication destruction.
This could have caused the reported crash.

Comment 2 Marcel Wiesweg 2008-12-30 21:26:24 UTC

Well the "Scan For New Images" tool has no direct and obvious connection to this backtrace here. There may well be a crash there, I have committed a possible fix.
If you compile from SVN please try if this fixes your problem.

Roman,

Please compile digiKam source code from trunk and try again. 

Thanks in advance

Cannot repeat the problem with 0.10.0-beta8 (rev.: 904148M) after at least 10 retries.

Note: try to check your graphics/digikam/CMakeLists.txt for things that have to do with KEXIV2. The cmake message about a found kexiv2 is irritating. It took me a while to notice that the appropriate openSUSE devel package was missing. All libraries where logges as "found", but I was not "allowed" to compile graphics/digikam.

We all have to thank for your work.

And a happy new year!
