Bug 306511

Application: digikam (2.8.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:
Tried to start digikam as usual, but it crashes always (restarted my computer several times..). 

- Unusual behavior I noticed:
Digikam became unstabel after a regular update of my Linux Mint 13 system on july 7th. Before that it worked perfectly. No issues with other software than digikam

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
