Description of problem:

GNOME Control Center crashes when trying to use VPN settings menu.


Version-Release number of selected component (if applicable):

control-center-1:3.26.0-1.fc27


How reproducible:


Steps to Reproduce:

1. Install Private Internet Access VPN by using the pia-nm.sh file provided at:

https://helpdesk.privateinternetaccess.com/hc/en-us/articles/219660347-OpenVPN-setup-in-Fedora

2. Log into one of their servers through the NetworkManager applet in GNOME.

3. Go to VPN Settings and select the gear icon next to the server you use. Select (this might not be exact since I can't get into the menu without it crashing right now) "Connect Automatically" then exit.

4. Restart the computer.

5. At this point, note that the VPN does not connect automatically, but you can still connect manually. If you go to VPN Settings and click the gear icon, GNOME Control Center crashes. 

 

Actual results:

GNOME Control Center crashes.


Expected results:

The settings menu for my VPN connection pops up.

Running the Control Center from the terminal gives this as soon as you click the gear icon:
