Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.97
Qt Version: 4.8.5
Operating System: Linux 3.7.0-7-generic i686
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

in project neon plasma desktop is randomly crashing all the time - and this i reported in a few of my previous bug reports also. i dont know the exact reason, because it just happens - this time during watching a video clip on youtube full screen. when we exited fullscreen the plasma desktop was gone and dr. konqi was already patiently waiting to be filled upand sent to you. 

Yesterday i upgraded to 4.9.97 - i also use project neone - all the newest stuff. i filled that similar reports might be also helpful although this is a crash wshich is happening now even in the newest version.

thank you!

nice day

Simon

The crash can be reproduced every time.
