Solve the following python programming problem given the following code:
def referenceDied(self, method, reference) : 
    ' Internally used method to inform the Master process that a remote
            referenced object has died.
        ' 
    def eb(failure) : 
        if (not failure.check (PBConnectionLost)) : 
            log.err (failure) 
try : 
        self._avatar.callRemote (method, reference).addErrback (self) 
except (DeadReferenceError, PBConnectionLost) : 
        pass 

    
    

    Fix the buggy line: self._avatar.callRemote (method, reference).addErrback (self)
