New crash information added by DrKonqi

plasma-desktop (4.11.5) on KDE Platform 4.11.5 using Qt 4.8.5

- What I was doing when the application crashed:
I dragged the kwrite icon from the taskmanager onto a different virtual desktop on the pager widget

- Unusual behavior I noticed:
I got this crash and the desktop flashed for a few second, then everything was running fine again.
