Description Greg Sinsley 2011-05-09 21:41:14 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was downloading a podcast in Amorak and tried to exit. Amorak notified me that there as still a download in progress, so I waited for the download to finish. The status progressed till it hit 94%, then it stopped. After waiting a while I decided the download failed so I hit cancel download and exit. This caused Plasma to immediately crash.

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