Oops the problem was during the activation of a given connection not 
deactivation. For deactivation, we're doing exactly what you suggested.

This is the code snippet I'm talking about. It'll give an error when 
mac_address is None.

    def set_profile_state_up(nm_handle, profile):
        for conn in nm_handle.connections:
            if conn.settings.id == profile:
                for device in nm_handle.devices:
                    if device.hwaddress == conn.settings.mac_address:
                        nm_handle.activate_connection(conn, device)

We've also looked at nm-applet. Apparently it lists all the available 
connections for a specific type under all the specific device so I don't 
expect a solution to be available but you may have some good suggestions.

Thanks.
