                     the D-Bus daemon, when a plugin is installed and the user
                     immediately tries to use it, the VPN plugin's rules aren't
                     always loaded into dbus-daemon.  Those rules allow NM to
                     talk to the plugin.  Oops.  Work around that by explicitly
                     allowing NM to talk to VPN plugins here.
