            Bug ID: 401442
           Summary: Network manager crashes on start
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: ascaris at q.com
  Target Milestone: ---

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
