List of Links extra results
The Special:Whatlinkshere page lists non-wiki pages in the wiki articles section of the page. The text for the links is missing the namespaces, and it implies that forum threads are wiki articles.
Fixed for the next build. When doing a general fetch of permissable wiki forums based on a list of namespace IDs, the function did not skip the Special namespace which did not have any associated forums, and resulted in a return of all forums.
