Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: Trying to shut down my laptop via KDE menu.

- Unusual behavior I noticed:  Everytime i've been doing this since this week's upgrade KDE always crashes on shutdown

- Custom settings of the application:  I'm not sure how to answer this question.

The crash can be reproduced every time.

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