Description Ouissal Benameur 2017-06-02 12:57:45 UTC 
Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.62-18.6-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
I had multiple Kwrite windows open (they were grouped, and over 5 windows), so when I right clicked and clicked on "close" to close them all, plasma crushed.
It happened twice now.

The crash can be reproduced sometimes.

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