Here it is:

import copy

class Test(int):
    def __new__(cls, arg1, arg2):
        return int.__new__(cls, arg1)

    def __init__(self, arg1, arg2):
        self.arg2 = arg2

if __name__ == '__main__':
    t = Test(0, 0)
    t_copy = copy.copy(t)

Traceback (most recent call last):
  File "copytest.py", line 12, in <module>
    t_copy = copy.copy(t)
  File "/usr/lib/python2.5/copy.py", line 95, in copy
    return _reconstruct(x, rv, 0)
  File "/usr/lib/python2.5/copy.py", line 322, in _reconstruct
    y = callable(*args)
  File "/usr/lib/python2.5/copy_reg.py", line 92, in __newobj__
    return cls.__new__(cls, *args)
TypeError: __new__() takes exactly 3 arguments (2 given)
