Loading a feed generated with feed.phtml template

[splattater]

Doing this with method newFromUrl($url) of DSSN_Activity_Feed_Factory of lib-dssn-php causes a warning:

Warning: DOMDocument::load() [domdocument.load]: Extra content at the end of the document in http://xodx.local/?c=feed&a=getFeed&uri=http%3A%2F%2Fxodx.local%2F%3Fc%3Dresource%26id%3D72645a1c9a388a3dbc9f98ebf156d666, line: 2 in /var/www/xodx/libraries/lib-dssn-php/DSSN/Activity/Feed/Factory.php on line 28

The DOMDocument object doesn't get the needed information. The warning disappears by removing the line with link node (rel="hub") in feed.phtml.

Update: The warning doesn't dissapear by removing mentioned line.

Seems to be a problem with redirecting.

Save it in a file e.g. follow-redirect.patch and apply it with patch -p1 < follow-redirect.patch from the lib-dssn-php base directory.
