Comment 1 Dobrogi 2016-02-28 21:59:18 UTC
I can confirm the same happens to me on Arch Linux with:
- Plasma 5.5.4
- NetworkManager 1.0.10
- networkmanager-openvpn 1.0.8-1
- networkmanager-qt 5.19.0-1
- nm-connection-editor 1.0.10-1
- openvpn 2.3.9-1

I noticed that it happens only when openvpn connection is in my configured connections. When I moved VPN-config from /etc/NetworkManager/system-connections to another folder the problem disappeared. I could switch between wifi connections with no problem. When I moved it back it started happening again.

VPN config:
[connection]

If you could manage to run

kquitapp5 plasmashell
valgrind plasmashell

and reproduce the crash that would be really useful.

Sure, please find the enclosed. I've switched networks around 300 line. 
It started happening about 1 mounth ago. There have been several plasma 
updates since then. The VPN connection was configured long ago (1 year 
or so) and previously everything worked fine.

Best Regards
P.
