Solve the following python programming problem given the following code:
def test_enqueue_wait_partial_relay(self) : 
    env = Envelope ('sender@example.com', ['rcpt1@example.com', 'rcpt2@example.com', 'rcpt3@example.com']) 
    self.store.write (env, IsA (float)).AndReturn ('1234') 
    self.relay._attempt (env, 0).AndReturn ({ 
        'rcpt1@example.com' : None, 
        'rcpt2@example.com' : TransientRelayError ('transient', Reply ('450', 'transient')), 
        'rcpt3@example.com' : PermanentRelayError ('permanent', Reply ('550', 'permanent')), 
}) 
    self.store.increment_attempts ('1234') 
    self.store.set_timestamp ('1234', IsA (float)) 
    self.store.set_recipients_delivered ('1234', set ([0, 2])) 
    self.mox.ReplayAll () 
    def backoff(envelope, attempts) : 
        return 0 
def no_bounce(envelope, reply) : 
        return None 
queue = Queue (self.store, self.relay, backoff = self, bounce_factory = no_bounce, relay_pool = 5) 
    queue.enqueue (env) 
    queue.relay_pool.join () 

    
    

    Fix the buggy line: queue = Queue (self.store, self.relay, backoff = self, bounce_factory = no_bounce, relay_pool = 5)
