Screenshots and Logs from two different hosts

SUMMARY
Duplicate network entries without names in the plasma-nm applet

STEPS TO REPRODUCE
1. Have at least one connection defined in NetworkManager.
2. Open up the plasma-nm applet from the System Tray.

OBSERVED RESULT
Available connections are listed, alongside "ghost" connections without any name or stats only with a "Disconnect" button.
The number of "ghost" connections is equal to the actual connections.
See example screenshots from two different Arch systems and outputs of 'journalctl | grep --line-buffered kde' from when the bug occurs.

EXPECTED RESULT
Actually available connections are shown without "ghost" duplicates.
