Bug 235281

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Once the widget had my credentials and tried to log in (or maybe it was when it was accessing kwalled) it brought down my entire desktop.  Oddly enough I can still alt-tab and work with what's running though.

The crash can be reproduced every time.

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