Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to add a predefined panel on the desktop via desktop menu with right click of mouse.
- Unusual behavior I noticed:
I noticed some thin coloured lines right up side of the screen before the crash. I have an ATI vga card with added drivers installed. It could be a video card problem?

The crash can be reproduced every time.

-- Backtrace:
Application: Shell del desktop di Plasma (plasma-desktop), signal: Segmentation fault
