Application: digikam (3.3.0)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.11.0-4-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I started batch conversion of around 1k of photos, saving it to original album, than
switched to the main window (which was displaing the album that was being converted in the background) and
changed the display mode from thumbnails to table after that digikam crashes
I tried 3 times to reproduce this bug and all 3 times was successful.

The crash can be reproduced every time.

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