Bug 385613

Application: kcmshell5 (5.8.7)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:
Trying to set up an wifi-ap in NetworkManager. NetworkManager crashes when pressing "OK" after editing the wifi settings of the ap-hotspot
The set-up wifi is visible in the connection manager of the Linux host, but not on mobile devices (two different were tested).

The crash can be reproduced every time.

-- Backtrace:
Application: Modul für Systemeinstellungen (kcmshell5), signal: Segmentation fault
