Bug 390448

Application: systemsettings5 (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to work on the network settings. Just clicking on "Connections" the App crashed at once. Repeating shows the same result every time. The App opens for a second and is closing almost instantly.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
