	* src/nm-manager.c
		- (free_get_settings_info): don't use the DBusGProxy which could be
			disposed of by the time the function is called
		- (internal_new_connection_cb): save connection scope
		- (connection_get_settings_cb): don't replace a connection unless it's
			actually different from the existing one; fixes an issue where
			killing the settings service wouldn't deactivate an active connection
			provided by that settings service, because it was using a connection
			that had already been replaced in the system or user hash
