Bug 255078

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
I have one user registered in kubuntu. Everytime it starts, plasma crash. The problem is gone if I delete .kde folder.
The last thing I did is to register my MSN account in kopete.

The crash can be reproduced every time.
