Bug 280210

Application: digikam (2.0.0)
KDE Platform Version: 4.7.00 (4.7.0) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-drm+ i686
Distribution (Platform): Gentoo Packages

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

After clean startup, I just switch from miniatures to view image (with doubleclick on the image) and click on the toolbar to switch to fullscreen. Application crashes while doing so.

The crash can be reproduced every time.

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