Bug 302178

Application: digikam (2.5.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic-pae i686
Distribution: Ubuntu 12.04 LTS

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

I was importing a big collection of files (all types of them: jpeg, nef, cr2). The import had already taken quite some time, maybe 10 minutes or something like that.Suddenly the application crashed.

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