Summary: forcing function to act like an unbound method dumps core

Initial Comment:
Using ActivePython, v2.2.2

I was reading PEP252 and trying stupid things, like this:

k [ 0:51] python
ActivePython 2.2.2 Build 224 (ActiveState Corp.) based 
on
Python 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more 
information.
>>> def func(): pass
...
>>> f = func.__get__()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: function takes at least 1 argument (0 given)
>>> f = func.__get__(None)
>>> f()    # This gives a reasonable result
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: unbound method func() must be called with ? 
instance as first argument (got nothing instead)
>>> f(1)    # This crashes accessing a null pointer
