Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-30-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
Waiting for Google Maps in Firefox to load the satellite view, was taking ages. Clicked the Application Launcher icon, typed system, clicked on KSysGuard, crash/boom. Not sure how related these events are, Plasma crashes a lot for me.

The crash can be reproduced sometimes.

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