Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.2
Qt Version: 4.8.3
Operating System: Linux 3.7.10-030710-generic x86_64
Distribution: Ubuntu-Secure-Remix 12.10 30nov2012

-- Information about the crash:
- What I was doing when the application crashed:
I had rebooted the machine to play a game in "otheros", found one of three activities I wanted open was stopped, activated that, got a plasma desktop crash.
- Unusual behavior I noticed:
I did not close the one activity I had to "start" before rebooting. I wasn't working in it either at the moment I logged out (well, Xcrash, possibly thanks to amd catalyst beta driver, happened occasionally before - still to find time to find out what that is.), so it is odd that it was stopped.

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