Summary: classmethod().__get__() segfault

Initial Comment:
Calling the __get__ method of a classmethod object 
with a single argument causes a segmentation fault in 
the interpreter :

  def f(): pass
  classmethod(f).__get__(0)

This is caused by an internal inconsistency between 
the __get__ wrapper function in C that calls the 
tp_descr_get slot with a NULL third argument in this 
case and some tp_descr_get slot implementations (like 
the classmethods') which dereference it with no check.
