Emitted when this proxy has been become invalid for whatever reason.
Any more specific signal should be emitted first.
An invalidated proxy is one which can make no more method calls and will emit no more D-Bus signals. This is typically because the D-Bus object represented by the proxy ceased to exist, or there was some error obtaining the initial state.
Any pending or future method calls made on this proxy will fail gracefully with the same error as returned by get_invalidated.
