Description bin 2016-02-26 14:32:11 UTC 
Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.3.5-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on the menu and was hunting through the program categories - drawing of sub-menus seemed to hang for about a second (stopped with just menu borders drawn, no contents), then Plasma crashed and restarted.
This happens occasionally (typically at least once per day).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
