-- 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
