When using VPN connections, plasma-nm also displays the tunnel device that is used (see screenshot). I did not check whether the problem also occurs with connections that use a tap-device. Reproducible: Always Steps to Reproduce: 1. Activate a VPN connection that uses a tun-device. Actual Results: Additionaly to the activated connection the applet displays a connection for the tun-device (e.g. tun0). Disconnecting this connection breaks the VPN without clearing routes, so that its not possible to access the internet anymore. Expected Results: Only one entry should be displayed.
