23408,Link to rss-feed in default installation causes redirect loop,clusterone,,"I noticed, that google webmastertools complained about dead links in my blog.
Those links were hidden in the html-code and were links to rss-feeds of attachments. (e.g. ?attachment_id=1647&feed=rss2)
When i try to open the link, it returns a 301 error and if the new url is called, anoter 301 error is shown. After two or three times, the original url is shown again by a 301 error message.

I installed two clean installations on different servers, which show the behaviour either. If i use the link ""?attachment_id=1647&feed=rss""  the correct feed is loaded. (using rss instead of rss2 which is provided by the template)

It seems that the error is caused by the function get_post_comments_feed_link(...) in ""wp-include/link-template.php used wp-include/canonical.php.
When i add another line to the function to return a link with ""attachment_id="" and not ""p="" or ""page_id"", the comment feed is loaded without errors.
But the fact, that rss feeds do not cause an error and rss2 feeds create a loop makes me think, that another module may be defect and my workaround is not a solution.
