I don't see this on my Win98 machine.  The code at that point is trying to
extract the port number.  It found the ":", but host[i+1:] seems to be
null.  If you want to play with this, you might try inserting some print
statements in set_hostport in httplib.py to print the vaue of host and of i
before that statement.
