Summary: socket.getnameinfo crashes interpreter

Initial Comment:
When making an invalid call to socket.getnameinfo() it
is possible to crash the interpreter.  From what I've
seen, this occurs under Windows ME with Python 2.2b1
and Windows 98 with Python 2.2a3.  It does not occur
under Mandrake 8.0 with Python 2.2a3.

>>> import socket
>>> socket.getnameinfo(socket.inet_aton('127.0.0.1'), 0)

This results with Python causing an error in
MSVCRT.DLL.  Under Mandrake 8.0 it causes the expected
exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
SystemError: new style getargs format but argument is
not a tuple

I cannot reproduce this in 2.2b1 (it works the same on 
Win32 as it does on Linux), but I also fail to see what 
code change may have caused to fail it in 2.2a3.

Please update to 2.2b1 and retest; if it still happens, 
check that you don't have any extra copies of 
python22.dll. If so, please add a note in this report, and 
we'll re-open it.

If you can, it would help enourmously if you could run the 
program in a debugger and report the stack trace in case 
of error, and the file and line number causing the crash.
