Bug 254382

Application: plasma-netbook (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I have been happening very often today, and a system restart is needed almost every half an hour. The plasma bar freezes turning it impossible to switch between aplications, or even minimise any window. Very annoying. good luck fixing it. Long life for (k)ununtu !

The crash can be reproduced every time.

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