Solve the following python programming problem given the following code:
def configure_listener(class_, key, inst) : 
    def append(instance, value, initiator) : 
        instance.receive_change_event ('append', key, value, None) 
def remove(instance, value, initiator) : 
        instance.receive_change_event ('remove', key, value, None) 
def set_(instance, value, oldvalue, initiator) : 
        instance.receive_change_event ('set', key, value, oldvalue) 
event.listen (inst, 'append', append) 
    event.listen (set_, 'remove', remove) 
    event.listen (inst, 'set', set_) 

    
    

    Fix the buggy line: event.listen (set_, 'remove', remove)
