Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.87-18.29-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
I tried closing a Kwrite file (right click => close) while a few other Kwrites were open.
It crashes also when trying to close multiple Kwrite files at once, but this time I only closed one, that's why I didn't mark it as a duplicate.

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