Bug 1164449

Same here.  Can't do VPN editing or adding.  How can one adjust these things manually?

In the way of logs, there are few.  If I run gnome-control-center from a command prompt, the following is thrown when I attempt to create or import an OpenVPN connection.

** (gnome-control-center:2216): WARNING **: Couldn't load builder file: (unknown)

Don't see any other relevant logging, if anyone can help me with that I'd be happy to provide it.

I have the same problem.
If I run "nm-connection-editor" from a terminal I recieve the following output:

[crosell@localhost ~]$ nm-connection-editor

Turns out that the Glade xml file is invalid. GtkGrid, unlike GtkTable, does not have the properties "n_rows" or "n_columns". Why this yields en fatal error I do not know. However, simply removing these 12 lines on 6 locations from the xml file seems to solve the problem. Also open the XML file in a later version of Glade and re-save it also solves the problem but generates more changes to the file.

There are still some layout issues with the OpenVPN dialog, caused by a very long label. But with this change the dialog works at-least.

Created attachment 960091 [details]
Glade XML file resaved in Glade 3.18.3

To use this file instead: Replace the "nm-openvpn-dialog.ui" file in the "/usr/share/gnome-vpn-properties/openvpn/" folder.

Claes Rosell's attachment seems to resolve the issue.

Is there a reason this change hasn't been made, and a new package built?

I also hit the problem on F21
