Bug 227387

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
First of all, in the energy preferences, I chose that when the laptop lid closes, it should block the screen, and it did. But then I used kpackagekit to update my system, closed the lid and left it working. When I came back and openend the lid. The message "The screen is blocked, enter our password appeared". I did, but inmediately after that plasma crashed. After that I rebooted my laptop but plasma crashes over and over again.

The crash can be reproduced every time.
