-- Information about the crash:
I just updated to kdemod 4.4 and right after I login (via the console console) and get to my desktop plasma crashes with signal 11. I had one plasmoid installed that I use regulary (YAWP) and removed it but plasma still crashes.

The crash can be reproduced every time.

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