Bug 401442

Application: kcmshell5 (5.14.3)

Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-42-generic x86_64
Distribution: KDE neon User Edition 5.14

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

I had just plugged in a USB3 Gigabit (Realtek 8153) network adapter (no ethernet cord; system has its own ethernet built in, and that is plugged in) and attempted to start the network manager applet via the tray icon.  It crashes every time I try.

The crash can be reproduced every time.

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