Solve the following python programming problem given the following code:
def test_materialize_never(self) : 
    scheduler = TestScheduler () 
    def create() : 
        return Observable.never ().materialize () 
results = scheduler.start (scheduler) 
    results.messages.assert_equal () 

    
    

    Fix the buggy line: results = scheduler.start (scheduler)
