Reproducible: Always

Steps to Reproduce:
1. click on the network icon on the systray
2. click on the button "configure network connections" from the flyout
3. select a saved connection and
4. click on the "edit" button

Actual Results:

It's also impossible to connect to a previously saved connection from the systray flyout's list of connections. You would have to open the connection editor and delete the connection before you can connect to it as a "new" connection.
