The name of Category:Hidden categories is translated according to the user interface setting, however, http://de.wikipedia.org/w/index.php?title=Kategorie:Hidden_categories is empty, while http://de.wikipedia.org/wiki/Kategorie:Versteckte_Kategorien has some categories. Moreover, the german translation should be „Versteckte Kategorie“, since we are using singular category names on de-wp. Maybe a MediaWiki page containing the name of this category would be useful.
