Summary: Setting __class__ to NoneType

Initial Comment:
Creating an instance, setting its __class__ attribute
to NoneType, and then allowing that instance to be
garbage collected crashes the interpreter with an
"Aborted" message.

Example:

>>> o = object()
>>> o.__class__ = type(None)
>>> del o
Aborted

This seems to be fixed on the trunk but still broken on the 
release22-maint branch.

I'll dig, but not when I'm stuck behind a modem, so I won't be offended
if someone beats me to it!
