When you access the search page of the german wikipedia via https https://secure.wikimedia.org/wikipedia/de/w/index.php?title=Spezial%3ASuche every search will bring you to a "Wiki does not exist" page. This is due to a wrong address in the action="..." attribute of the html form and should be easy to fix.
That is not a bug in MediaWiki, but in the custom script on the German Wikipedia (http://de.wikipedia.org/wiki/MediaWiki:SpezialSuche.js). I added a note at http://de.wikipedia.org/wiki/MediaWiki_Diskussion:SpezialSuche.js#This_breaks_secure_access – feel free to discuss there.
