Bug 289782

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: unlock widgets, click on the 'kidney' on the panel, click 'Add Widgets', click 'Categories', select 'Running'.  'System Tray' is there, I click accidentally on 'Sastem Tray' again -> crash of the plasma workspace(?).

-- Backtrace:
Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Segmentation fault
