Solve the following python programming problem given the following code:
@ classmethod 
def _get_pseudo_instance(cls) : 
    'Overloaded method returning the DEFAULT_CONFIG with added methods
        ' 
    def save_unitialized(filename) : 
        'Saves an unitialized config
            ' 
        cls.initialize () 
        cls.get_instance ().save (filename) 
cls.DEFAULT_CONFIG.reset_instance = Config.reset_instance 
    cls.DEFAULT_CONFIG.load = cls.initialize 
    cls.DEFAULT_CONFIG.save = save_unitialized 
    return save_unitialized.DEFAULT_CONFIG 

    
    

    Fix the buggy line: return save_unitialized.DEFAULT_CONFIG

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