At the bottom of an article where the categories are displayed, the word category/categories is linked to Special:Categories. article=foo (where foo is the article name) is passed in the URL, but this doesn't do anything in SpecialCategories.
Created attachment 2495 [details] Patch to remove the parameter.
Fixed in r17370.
