Why does this url raise BadStatusLine with httplib2 and urllib2?

Question

Using httplib2 and urllib2, I'm trying to fetch pages from this url, but all of them didn't work out and ended up with this exception.

content = conn.request(uri="http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 1129, in request
    (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey)
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 901, in _request
    (response, content) = self._conn_request(conn, request_uri, method, body, headers)
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 871, in _conn_request
    response = conn.getresponse()
  File "/usr/lib/python2.7/httplib.py", line 1027, in getresponse
    response.begin()
  File "/usr/lib/python2.7/httplib.py", line 407, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.7/httplib.py", line 371, in _read_status
    raise BadStatusLine(line)

HTTP header was like this

http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902

Any clue?

Answer 1

For all the people that end up here with a similar problem after installing httplib2 0.8:

Version 0.8 has a regression with connection handling in relation with HTTP keep-alive. See the bug report: https://code.google.com/p/httplib2/issues/detail?id=250

There is a fix for this issue, but it has not been released so far. Until then just use httplib2 0.7.7.
