Unable to add a vpnc connection.

Steps to Reproduce:
1. Open Networks Settings
2. Add VPN (plus button)
3. Choose Cisco Compatible VPN (vpnc)
4. Fill out "Gateway"
5. Fill out "User name"
6. Write a single letter in "Group name" (or paste a whole string)
7. See the "Add" button become active
8a. Change a single character in "Group name"...
8b. or open "Advanced..." modal and close it again.
The "Add" button becomes inactive and never becomes active again.
The "Add" button stays active until the form fields are "invalid"
Workaround is to fill "Group name" last.
