Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Some other window was active, and when I clicked on a Firefox window, I got a Plasma crash.
It restarted afterwards, and everything was fine.
I get these crashes a few times every day.

The crash can be reproduced sometimes.

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