Bug 249350

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

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

Each time I restart the system, the desktop wallpaper is the default one. Only when I right-click and choose the image to appear, it does. But then the application crashes. In spite of that, I can continue working normally.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
