Description Aaron Peterson 2014-09-01 11:49:11 UTC 
Application: plasmashell ()

Qt Version: 5.3.2
Operating System: Linux 3.13.0-35-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
resized the virtual machines window (running in virtualbox 
- Unusual behavior I noticed:
Many crashes thru any use of these machines
- Custom settings of the application:
I disable all animations and silly effects.
I also put the  panel on the left
Sometimes after a crash the panel is made skinny again, when I had previously set it as thick.

I also get some error about vlc backend.

Using a project neon from within 24 hours.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
