Bug Description

While trying to create new OpenVPN connection the connection enters seems to enter an infinite loop printing the following to stderr:

** (nm-connection-editor:2535): WARNING **: Invalid setting VPN: cert

It repeats these lines over and over.

The UI is unresponsive during this making it impossible to configure a VPN connection.

There seems to be a problem handling the .p12 files, when .p12 file is exploded into ca/client-key/client-cert .pem file the UI works properly.

Yes, still exists in 14.04 LTS and so far I've found no solution for it. Pfsense exports keys in p12 format and it should affect a lot of users.

The problem is simply how the dialog UI manages fields "user", "cert", "key" to be sure that either all of them contain the same pkcs12 file path or none of them contain it. This is implemented with event handlers triggered when field selections change.
Unfortunately this handlers are triggered in such a way that an endless loop occurs.

The affected library is /usr/lib/NetworkManager/libnm-openvpn-properties.so of package NetworkManager-openvpn-0.9.8.2

A patch is attached for the source properties/auth-helpers.c

Here it is a patched libnm-openvpn-properties.so you can test by replacing the one in /usr/lib/NetworkManager

Hi, I just tested the patched libnm-openvpn-propterties.so and I can confirm that for me, it now works (while it did _not_ work with the unpatched .so).
