Bug 384273

Application: kcmshell5 (5.10.5)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.8-300.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed: I was attempting to change the network that my computer was connected to. First I tried by clicking on the shortcut in the system tray. It also crashed when opening Sytem Settings and selecting Connections under the Network category.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
