Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I had just closed down Kontact to save Akregator read state (because of a bug in Ubuntus qtwebkit that causes it to crash randomly). Korgac started its notification frenzy from https://bugs.kde.org/show_bug.cgi?id=250729 and before I got to kill it Plasma crashed.

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