Application: plasma-desktop (4.11.20)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 4.2.1-1.g9c7cacf-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Kaffeine did hang (presumably for a dvb-t signal issue. When I closed it the whole desktop froze, stayed frozen for a while, then came back to life and konqi popped up. Only after this, the application Kaffeine that I had tried to reopen, did come up. 
- Unusual behavior I noticed:
Unlike other Plasma crashes I had the desktop did NOT become black. It just stayed frozen. But the desktop was visible and also the two monitor support was active. But now action was possible.

-- Backtrace:
Application: Shell del desktop di Plasma (plasma-desktop), signal: Segmentation fault
