Solve the following python programming problem given the following code:
def _event_emit_delayed(self, event) : 
    'Emit events - possibly delayed.' 
    def event_cleanup(gt, * args, **kwargs) : 
        'Callback function for greenthread. Called
            to cleanup the _events_delayed dictionary when an event
            was called.
            ' 
        event = args [0] 
        self._events_delayed.pop (event.uuid, None) 
if (event.uuid in self._events_delayed.keys ()) : 
        self._events_delayed [event.uuid].cancel () 
        self._events_delayed.pop (event.uuid, None) 
        LOG.debug ('Removed pending event for %s due to lifecycle event', event.uuid) 
if (event.transition == virtevent.EVENT_LIFECYCLE_STOPPED) : 
        id_ = greenthread.spawn_after (self._lifecycle_delay, self._event_emit, event) 
        self._events_delayed [event.uuid] = id_ 
        id_.link (event_cleanup, self) 
else : 
        self._event_emit (event) 

    
    

    Fix the buggy line: id_.link (event_cleanup, self)

#Here is Python code to fix the buggy line: id_.

id_.link (event_cleanup, event)
