urllib2 crashes with stack trace on legal URL http://118114.cn
Transcript:
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2

>>> import urllib2
>>> urllib2.urlopen("http://118114.cn";)
Traceback (most recent call last):

I think the problem is that "http://118114.cn"; says it redirects to
"http://www.118114.cn:";, but it seems like urllib2 should be able to deal with
that or at least report back a more useful error message.
