A socket's sendto method can be tricked into a
SystemError exception. This happens with:
Linux special 2.4.29 #19 Thu Jan 27 20:51:25 CET 2005
i686 unknown
and
Python 2.4.2 (#2, Dec 27 2005, 11:06:14)
but:
Linux vesuv6 2.4.20-4GB #1 Mon Mar 17 17:54:44 UTC 2003
i686 unknown unknown GNU/Linux
Python 2.3.3 (#1, Jun 29 2004, 14:43:40)

shows the same behaviour.
These 4 lines demonstrate the failure:
import socket
s = socket.socket( socket.PF_PACKET, socket.SOCK_RAW,
 socket.htons(
0x0003 ) )
s.sendto( "abc", 0, range( 6 ) )
yields:
Traceback (most recent call last):
 File "serr.py", line 7, in ?
 s.sendto( "abc", 0, range( 6 ) )
SystemError: new style getargs format but argument is

Well, 'tricked' is a bit of a big word; it just means you
passed the wrong type of address; AF_PACKET expects a tuple
(of string+int or int+int+string), and not a list. It didn't
have any ill effects (other than confusing the programmer.)
I fixed the errormessage for AF_PACKET (and AF_INET6, which
was also missing) in trunk revision 45714 (so it'll be in
2.5 alpha 2.) Thanks!
