The tab of all pages (Special:allpages) include a link to itself.
This link is not useful, but cause the crawler a lots of trouble.
Pretty much all pages have a link to themselves as the first tab (or second for
discussion). This can be used when you're using nonstandard URL options like
skin choices, have been redirected and want to go to the real URL for some
Note that pages can also include links for paging and limiting, and so forth,
which also link back to the same page.
