Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

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

- Unusual behavior I noticed: desktop occasionaly hangs with no activity going on, no processor load visible, usually recovers after 5-10 minutes. Amd e350 apu with default opensuse drivers

The crash can be reproduced some of the time.

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