Bug 254578

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: I updated OS via apt-get, when KPackageKit started to work. I clicked on update. KPackageKit found no new packages (because the system was already updated via apt-get). Then KPackageKit appeared two times in SystemTray. When I clicked on one of the icons Plasma crashed.

- Unusual behavior I noticed: KPackageKit appears two times in system tray.

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