Application: digikam (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Starting Digikam. Crash occurrs regardless of config files, database, empty library etc. during the splash screen at phase "initialising main view"

Behaviour started a few days after an apparently succesful upgrade to Kubuntu 12.04, but Digikam was working after the upgrade.

- Custom settings of the application:
Crash always occurs in the same place during start up even if config files are removed

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Bus error
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
