Sentry Crash Report:

Description Scarlett Moore 2015-04-08 14:53:14 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-12-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed: Anything really, it almost seems like it is 
crashing on notifications. But I have not had time to stare at it to confirm. If I remove the systray from the panel
all is well, well except I do not have a systray.

- Unusual behavior I noticed: Panel bar suddenly goes crazy and starts redrawing itself.

The crash can be reproduced every time.

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