Bug 245178

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-23-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I just opened Firefox and it crashes.  I turn on Kubuntu and it crashes.  There's really nothing else to say.  It crashes after the basic operations.  The widgets i have open are the desktop viewer, Facebook, and the microblogger.

The crash can be reproduced every time.

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