Bug 277198

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-02063901-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
Plasma crashes on me at random, about once a day.  This time when it crashed,  I was merely browsing the web in Chromium.  VirtualBox and Novell Groupwise were running on my desktop at the time, but not in use.

This is 64-bit Kubuntu Natty upgraded to KDE 4.6.4

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
