This happens when redirected URL contains fragment.

urllib2.Request.get_selector() should be:

    def get_selector(self):
        return self.__r_host.split('#')[0]

Fixed in revision 83818(py3k),  83819 (release31-maint) and 83820 (release27-maint).

David, a couple of comments on your patch.
- Request method was from urllib2, so the proper place of tests were test_urllib2. This already had Requests test so some additional tests were only required.
- Also, now the fragments are removed and sent to the server, a proper response could be obtained, it can tested via 'network' tests in test_urllib2net.

You might check the svn diffs to see the changes made. 
Thanks for the patch.
