Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.79-19-default x86_64
Distribution: "openSUSE Leap 42.3"

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

Every time I run a bash script which is opening about 20 gkrellm windows plasma crashes.

The crash can be reproduced every time.
