Bug 269118

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.38-7-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
This may very well be a duplicate of bug # 268157, but this is currently hard to verify for me considering my system is in the middle of a shutdown with just the crash reporter open...

- What I was doing when the application crashed:

Restarted the system via the "Lock/Logout" Plasmoid.

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