Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-66-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

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

Simply clicking on it when, when it tries to start a crash window comes up. I'm connected to wifi and lan in the same time currently.

The crash can be reproduced every time.
