-- Information about the crash:
kde 4.4.3 crashes on restart
I was restarting Kubuntu 10.04 LTS and crash report assistant popped up 
having in mind the bug with the ugly logo with nvidia drivers and the problems with the task bar kubuntu 10.04 lts is not deserving the lts sign it is a half baked product (more like beta 1) or kde 4 is not ready yet.....

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