Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was monitoring Xorgs memory usage becuase I suspect that plasma-desktop makes it grow to absurd sizes, so I opened three activities, switched between all of them and then added a bunch of widgets to the third activity.  I then removed them all, and one by one "stopped" all the activities exept the first one.  Then, with the activity bar still open, I switched desktops with pager.  Xorg's memory immediatly tripled (going from 40mb to 120mb) and plasma crashed.

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