Description d_blatne 2013-04-25 15:50:05 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Klicked on Add Widget at the menu bar, then typed 'dash' and dragged the "Show Dashboard" Widget to the menu bar beside the "Show Desktop" Widget.

- Unusual behavior I noticed:
While dragging over the "Show Desktop" Widget, the desktop showing widget was activated, showed the desktop and kde crashed when I released the mouse button.
