KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
After latest KDE4.6.3 updates on Debian Sid, Plasma still crashes on every shutdown, logout, or reboot using any of the shutdown widgets or when using the shutdown options from the main KDE menu.

The crash can be reproduced every time.
