New submission from yoch:

Hi,

If some class objects have extra arguments in the __new__ constructor , pickle fail to serialize it.

Here the output of provided test-case :

Traceback (most recent call last):
  File "/home/yoch/bug.py", line 19, in <module>
    y = pickle.load(fp)
TypeError: __new__() missing 1 required positional argument: 'arg'

Best regards
