Solve the following python programming problem given the following code:
def _output_loop(self) : 
    from twisted.internet import reactor 
    if (self.stopped is True) : 
        if (self.outputting_d is not None) : 
            self.outputting_d.callback (True) 
            self.outputting_d = None 
return 
blobs = self.download_manager.blobs 
    log.info ('In _output_loop. last_blob_outputted: %s', str (self.last_blob_outputted)) 
    if blobs : 
        log.debug ('Newest blob number: %s', str (max (blobs.iterkeys ()))) 
if (self.outputting_d is None) : 
        self.outputting_d = defer.Deferred () 
current_blob_num = (self.last_blob_outputted + 1) 
    def finished_outputting_blob() : 
        self.last_blob_outputted += 1 
        final_blob_num = self.download_manager.final_blob_num () 
        if ((final_blob_num is not None) and (final_blob_num == self.last_blob_outputted)) : 
            self._finished_outputting () 
            self.outputting_d.callback (True) 
            self.outputting_d = None 
else : 
            reactor.callLater (0, self._output_loop) 
if ((current_blob_num in blobs) and blobs [current_blob_num].is_validated ()) : 
        log.info ('Outputting blob %s', str (current_blob_num)) 
        self.provided_blob_nums.append (current_blob_num) 
        d = self.download_manager.handle_blob (current_blob_num) 
        d.addCallback ((lambda _ : finished_outputting_blob ())) 
        d.addCallback ((lambda _ : self._finished_with_blob (current_blob_num))) 
else : 
        if (blobs and (max (blobs.iterkeys ()) > ((self.last_blob_outputted + self.max_before_skip_ahead) - 1))) : 
            self.last_blob_outputted += 1 
            log.info ('Skipping blob number %s due to knowing about blob number %s', str (blobs.last_blob_outputted), str (max (blobs.iterkeys ()))) 
            self._finished_with_blob (current_blob_num) 
            reactor.callLater (0, self._output_loop) 
else : 
            self.outputting_d.callback (True) 
            self.outputting_d = None 

    
    

    Fix the buggy line: log.info ('Skipping blob number %s due to knowing about blob number %s', str (blobs.last_blob_outputted), str (max (blobs.iterkeys ())))

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

log.info ('Skipping blob number %s due to knowing about blob number %s', str (self.last_blob_outputted), str (max (blobs.iterkeys ())))
