Bug 290873

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 i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I had closed several open mozilla (firefox, Aurora, nightly build) windows and the firefox app was still listed in taskmanager. When I clicked on it, it said "firefox (0)", so I right click to see if it had something to do with Acivityies.. 

Crash upon right-click

Landis.

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