This is obviously a silly thing to do:

>>> classmethod(1).__get__(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
SystemError: ../Objects/classobject.c:2102: bad
argument to internal function

but I think that's still a bug.

Well, couldn't we check if the argument is a non-data descriptor 
at least?  Since classmethod only works with new-style we know 
the method will be a non-data descriptor.  That should prevent 
allowing arguments like 1 being allowed through.

Added a callability check.
