Comment 1 Lamarque V. Souza 2016-10-10 01:36:07 UTC
This crash happens inside Qt. As far as I know no KDE software uses QNetworkManagerInterfaceAccessPoint class. What plasmoid do you use to manage network connections?
Comment 2 Marcus Better 2016-10-10 01:38:40 UTC
I believe I'm using the plasma-nm Debian package with the network manager applet in the panel.
Comment 3 Lamarque V. Souza 2016-10-10 03:10:28 UTC
plasma-nm does not use QNetworkManagerInterfaceAccessPoint class, which is the class where the crash happened according to the backtrace.  Send me a screenshot of your desktop's panel, so I can see the applets you are using.
