For what it's worth, I've had a similar problem with the urlopen as
well. Using the library default urlopen results in an error, but if I
build an opener with the basic handlers, it works just fine.

>>> import urllib2
>>> f = urllib2.urlopen("http://localhost:8000")
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    f = urllib2.urlopen("http://localhost:8000")
  File "C:\Python25\lib\urllib2.py", line 121, in urlopen
    return _opener.open(url, data)
  File "C:\Python25\lib\urllib2.py", line 380, in open
    response = meth(req, response)
  File "C:\Python25\lib\urllib2.py", line 491, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:\Python25\lib\urllib2.py", line 418, in error
    return self._call_chain(*args)
  File "C:\Python25\lib\urllib2.py", line 353, in _call_chain
    result = func(*args)
  File "C:\Python25\lib\urllib2.py", line 499, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 403: Forbidden
>>> opener = urllib2.OpenerDirector()
>>> opener.add_handler(urllib2.HTTPHandler())
>>> opener.add_handler(urllib2.HTTPDefaultErrorHandler())
>>> f = opener.open("http://localhost:8000")
>>> f.read()
'something relevant'
