Bug 305517

Application: digikam (2.5.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I have selected pictures I whshed to export, but digikam immediately crashed after choosing Export - Export to Flash in its menu. Other export plugins worked fine.

The crash can be reproduced every time.

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