Solve the following python programming problem given the following code:
def _find_leafs_paths(self, structure, leafs_names = ('value',)) : 
    'Finds paths to leafs

        :param structure: structure for searching
        :param leafs_names: leafs names
        :return: list of tuples of dicts keys to leafs
        ' 
    def _keys_paths_helper(result, keys, struct) : 
        if isinstance (struct, dict) : 
            for k in sorted (six.iterkeys (struct)) : 
                if (k in leafs_names) : 
                    result.append (keys) 
else : 
                    _keys_paths_helper (result, (keys + (k,)), struct [k]) 
else : 
            if isinstance (struct, (tuple, list)) : 
                for d in struct : 
                    _keys_paths_helper (result, keys, d) 
else : 
                pass 
leafs_paths = [] 
    _keys_paths_helper (_keys_paths_helper, (), structure) 
    return self._remove_private_leafs_paths (leafs_paths) 

    
    

    Fix the buggy line: _keys_paths_helper (_keys_paths_helper, (), structure)

#Here is Python code to fix the buggy line: _keys_paths_helper (_keys_paths_helper, (), structure)
