Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed: shut down from KDE
- Funny behavior: between click on "shut down" and confirming of the shut-down-command desktop shows frozen and distorted "screen shots" of recently used programms...

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Segmentation fault
