Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I tried to close a few windows by clicking on an item of the task manager widget. My computer was quite busy, so it did not respond immediately. I clicked the item again and plasma crashed.

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