Solve the following python programming problem given the following code:
def test_descriptors(self) : 
    def original_dec(wrapped) : 
        def _wrapped(arg) : 
            return wrapped (arg) 
return _wrapped 
method_dec = method_decorator (method_dec) 
    class bound_wrapper (object) : 
        def __init__(self, wrapped) : 
            self.wrapped = wrapped 
            self.__name__ = wrapped.__name__ 
def __call__(self, arg) : 
            return self.wrapped (arg) 
def __get__(self, instance, cls = None) : 
            return self 
class descriptor_wrapper (object) : 
        def __init__(self, wrapped) : 
            self.wrapped = wrapped 
            self.__name__ = wrapped.__name__ 
def __get__(self, instance, cls = None) : 
            return bound_wrapper (self.wrapped.__get__ (instance, cls)) 
class Test (object) : 
        @ method_dec 
        @ descriptor_wrapper 
        def method(self, arg) : 
            return arg 
self.assertEqual (Test ().method (1), 1) 

    
    

    Fix the buggy line: method_dec = method_decorator (method_dec)

#Here is Python program to fix the buggy line: method_dec = method_decorator (method_dec)
.

method_dec = method_decorator (def original_dec()
