Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Just freshly booted, happens at random intervals, plasma ddesktop often restarts succesfully but occasionally crashes and does not start leaving applications still open but with a blank desktop.
- Unusual behavior I noticed:
Applications are still open and unaffected by crash. I do have the virus desktop background installed which seemed to cause other bugs like this.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
