Application: kcmshell5 (5.10.1)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

1. I opened the wireless connection menu in the panel
2. Clicked on the "Configure Network Connections..." icon
3. The Connections settings opened
4. After about 1 second, it crashed (perhaps I clicked one of the connections)

I tried repeating this few more times, and it did not happen again. This was the first time I booted with Plasma 5.10.1 / Qt 5.9

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
