New crash information added by DrKonqi

plasma-desktop (4.11.3) on KDE Platform 4.11.3 using Qt 4.8.5

- What I was doing when the application crashed:

Moving quicklaunch widget to the panel between Ativities and Task Manager widgets. Before releasing mouse button the crash happened. Only on first attempt.
