I can reproduce this. The server seems to send gzip encoded content, although 
wget did not send 'Accept-Encoding':

GET /index.php?title=Hauptseite&uselang=de HTTP/1.0
User-Agent: Wget/1.11.4
Accept: */*
Host: wiki.openstreetmap.org
Connection: Keep-Alive

HTTP/1.0 200 OK
Date: Fri, 28 Aug 2009 07:42:54 GMT
Server: Apache
X-Powered-By: PHP/5.2.4-2ubuntu5.6
Content-Language: en
ETag: W/"wiki:pcache:idhash:4416-0!1!0!!de!2!edit=0--20090828043909"
Vary: Accept-Encoding,Cookie
X-Vary-Options: Accept-Encoding;list-contains=gzip,Cookie;string-
contains=wikiToken;string-contains=wikiLoggedOut;string-contains=wiki_session
Cache-Control: s-maxage=18000, must-revalidate, max-age=0
Last-Modified: Fri, 28 Aug 2009 04:39:09 GMT
Content-Encoding: gzip
Content-Length: 13134
Content-Type: text/html; charset=UTF-8
Age: 1490
X-Cache: HIT from ross.wwood.co.uk
X-Cache-Lookup: HIT from ross.wwood.co.uk:3128
Via: 1.0 ross.wwood.co.uk:3128 (squid/2.6.STABLE18)
Connection: keep-alive

This is probably due to a misconfiguration of the proxy server; I think it is 
unlikely that MediaWiki is the cause.
