Application: digikam (1.0.0)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I installed digKam via my package manager. Every time I run digKam, I see the splash screen for one second or two and then the application crashs with the error "Signal 6 (aborted)". There seem to be some problems with dependencies (there is libkipi6 and libkipi7, libkexiv2-7 and libkexiv2-8, and so on...). DigiKam seems to need the older version of all libraries, but installs the newer one as dependency.

After reinstalling digiKam I was able to use it for five minutes until it crashed again (I was generating image finger prints). Since then I wasn't able to get it starting again.

The crash can be reproduced everytime.

 -- Backtrace:
Application: digiKam (digikam), signal: Aborted
