Solve the following python programming problem given the following code:
@ classmethod 
def _listen(cls, event_key, retval = False, **kw) : 
    fn = event_key._listen_fn 
    if (not retval) : 
        def wrap(* arg, **kw) : 
            if (not retval) : 
                query = arg [0] 
                fn (* arg, ** kw) 
                return query 
else : 
                return fn (* arg, ** kw) 
event_key = event_key.with_wrapper (event_key) 
event_key.base_listen (** kw) 

    
    

    Fix the buggy line: event_key = event_key.with_wrapper (event_key)

#Here is Python program to fix the buggy line: event_key = event_key.
