Reproducible: Always

Steps to Reproduce:
1. Connect to a WiFi network, wait till the connection is fully established
2. Pick another WiFi network from the plasman-nm widget menu
3. Plasma crashes (but NM itself works and switched the WiFi network correctly)

Actual Results:  
Plasma crashes

Expected Results:  
WiFi network gets switched without crashing plasma in the process

I get the came crash if I use the "Connect" button in the connection editor window. I can also get a similar crash when I try to establish a VPN connection etc. but they are more difficult to reproduce. The crash does not occur if the network is switched before the connection to the first WiFi is fully established.
