Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Returning to KDE desktop from term via Ctrl+Alt+F7; ran "killall drkongi, killall -9 kpackagekitsmarticon" in term for reasons below.
- Unusual behavior I noticed:
System was running slow. Opened system monitor and noticed kpackagekit was using a somewhat large amount of memory (> 56MB). Moused over blank area on taskbar where kpackagekit icon should have been, crash reporter appeared with information on segfault for kpackagekit over 100 times and HD began grinding.

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