Bug 261691

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-8-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Plasma crashes after any of these actions:
1) trying to change widget's settings (right after pressing Ok button) 
2) pointing mouse over the widget and waiting for about 1 sec

After this plasma restarts and works fine (crash can be made again via same actions). Settings still unchanged

100% reproducable 

The crash can be reproduced every time.

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