Description Martin Deppe 2017-11-10 21:32:33 UTC 
Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.92-18.36-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:

I am using Firefox 52.4.0 (64 Bit) which always crashes "Plasma desktop" when I close firefox.
My OS is openSuSE 42.2 and I am encounting this issue since quite a while now. I can't say whether it is a year already or even longer, but I don't think so.

The crash can be reproduced every time.

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