Bug 300603

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I've just booted kubuntu and clicked on the little light bulb - pop-up symbol wich mentiont available software updates, afterwards the plasma desktop crashed, but a few seconds later everthing worked fine again. This problem occurs in a slightly simliar way quite often, but instead of crashing the whole desktop there's just a big, black windows across the screen when I click on the update-symbol. I can just close the windows so it's not really a problem, but yes, kinda annoying.

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