KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.11.0-4-generic i686
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I was  trying to put a virtual desktop indicator widget on the taskbar, but dragging the widget icon onto the taskbar and a click seems to have caused the crash

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
