Solve the following python programming problem given the following code:
@ rerun_if_locked 
def _add_blobs_to_stream(self, stream_hash, blob_infos, ignore_duplicate_error = False) : 
    def add_blobs(transaction) : 
        for blob_info in blob_infos : 
            try : 
                transaction.execute ('insert into lbry_file_blobs values (?, ?, ?, ?, ?)', (blob_info.blob_hash, stream_hash, blob_info.blob_num, blob_info.iv, blob_info.length)) 
except sqlite3.IntegrityError : 
                if (ignore_duplicate_error is False) : 
                    raise 
return self.db_conn.runInteraction (ignore_duplicate_error) 

    
    

    Fix the buggy line: return self.db_conn.runInteraction (ignore_duplicate_error)

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