Bug 389319

Application: kcmshell5 (5.11.5)

Qt Version: 5.9.2
Frameworks Version: 5.42.0
Operating System: Linux 4.14.13-300.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
With nothing else open, opening the Network Settings module from the icon bar at the bottom of the screen displays the popup dialog for two or three seconds, which then disappears with the crash notification.

This happens every time I open it.

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