Solve the following python programming problem given the following code:
def _start_queue_management_thread(self) : 
    def weakref_cb(_, q = self._result_queue) : 
        q.put (None) 
if (self._queue_management_thread is None) : 
        self._queue_management_thread = threading.Thread (target = _queue_management_worker, args = (weakref.ref (self, weakref_cb), self._processes, self._pending_work_items, self._work_ids, weakref_cb._call_queue, self._result_queue)) 
        self._queue_management_thread.daemon = True 
        self._queue_management_thread.start () 
        _threads_queues [self._queue_management_thread] = self._result_queue 

    
    

    Fix the buggy line: self._queue_management_thread = threading.Thread (target = _queue_management_worker, args = (weakref.ref (self, weakref_cb), self._processes, self._pending_work_items, self._work_ids, weakref_cb._call_queue, self._result_queue))
