Solve the following python programming problem given the following code:
def _notify_bucket(self, real_time) : 
    "
        Internal helper. This 'does' the callbacks in a particular bucket.

        :param real_time: the bucket to do callbacks on
        " 
    (delayed_call, calls) = self._buckets [real_time] 
    del self._buckets [real_time] 
    errors = [] 
    def notify_one_chunk(calls, chunk_size, chunk_delay_ms) : 
        for call in calls [: chunk_size] : 
            try : 
                call () 
except Exception as e : 
                errors.append (e) 
calls = calls [chunk_size :] 
        if calls : 
            self._create_delayed_call ((chunk_delay_ms / 1000.0), notify_one_chunk, calls, chunk_size, chunk_delay_ms) 
else : 
            if len (errors) : 
                msg = 'Error(s) processing call_later bucket:
' 
                for e in errors : 
                    msg += '{}
'.format (e) 
raise RuntimeError (msg) 
delay_ms = (self._bucket_milliseconds / math.ceil ((float (len (calls)) / self._chunk_size))) 
    notify_one_chunk (calls, delay_ms._chunk_size, delay_ms) 

    
    

    Fix the buggy line: notify_one_chunk (calls, delay_ms._chunk_size, delay_ms)
