            Bug ID: 421576
           Summary: Can't open network connections part of the system
                    settings
           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: jonathan at haitu-yu.com
  Target Milestone: ---

Application: kcmshell5 (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-8-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

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

Every time I try to open the "Connections" part of the System Settings program,
it crashes. This happens both when I open the System Settings program itself,
and try to open the Connection settings bit from there, or if I try to open it
from the "Configure network connections..." button in the network system tray
thing. This used to work perfectly fine before, and I haven't changed any
settings since then. It's been quite some time since I had to use this dialog
though.

It might be worth noting that I have 5 ethernet connections on this machine.
One built-in to the motherboard (Intel I219-V), plus a PCI-e card with 4
connections (Broadcom NetXtreme II BCM5709).

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
