A Fatal Error Occurred

[Alex Makhlin]

Hi all,

I am running Fedora 9 / KDE 4.1 and after reboot I received this error 
when logging onto my main user "A Fatal Error Occurred" "The application 
Plasma Workspace (Plasma) crashed and caused the signal 11 (SIGSEGV). 
The root user is fine as well as other users but why the main one?  I 
backed up all my personal files and deleted my main user. Then I 
recreated it and reconfigured it to my personal settings and everything 
is fine. Anyone know why this happened? I didn't do anything but yet it 
crashed!
