Bug 343163

Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1 clicked add widget to panel
2 typed "virtual" for desktop selector widget
3 clicked and dragged the widget to the panel, first a little bit on task switcher widget because i wanted to locate the widget next to it
4 plasma crashes (imo before i released the mouse, so during drag)

I tried installing additional devel rpms but failed to fill in the empty spaces around libdraganddrop

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
