Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic x86_64

What I was doing when the application crashed:
Digikam crashed at least 4 times while saving an edited photo, or overwriting it (same thing) or when deleting a photo. It didn't happen each time, but happened quite often.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
