Bug 228346

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.22.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
This error began after upgrading KDE packages to the latest levels. 4.4. I checked the yum transaction and it all appears to have worked properly. KDE 4.4 packages upgraded etc. QT was upgraded to 4.6 etc. I don't see any errors in the transaction and running yum update finds no packages in need of being updated. 

The error is the same each time, I get the login screen, enter my password then enter. I hear the kde startup sound but then there is no desktop. KDE failsafe does not work either. The only way I am able to get in is via failsafe.

The crash can be reproduced every time.

Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
