Description:
System: AIX 5.3, Technical Level 5
DB: Postgesql 8.1.5
Webserver: Apache 2.2.3 with PHP 5.1.6
Mediawiki: Version 1.9.2, German language

The wiki uses German Language as Default. The actual used link is:
Spezial:%C3%84nderungen_an_verlinkten_Seiten/Hauptseite

For better understanding I set the language of the user English
with the same result.
