Bug 287325

Application: plasma-overlay (0.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I had added the pictureframe wigit and testing the screensaver (solar winds) 

- Custom settings of the application: I selected the slideshow option and then the screensaver crashed

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma for the Screensaver (plasma-overlay), signal: Segmentation fault
