Thread:Extension talk:Realnames/Realnames 0.3.1 page titel and body problem

First I got to say I am working in Austria.

I am running MW 1.18.0 with Realnames 0.3.1 and my problem is that every page titel in the header/body that starts with "Benutzer" is replaced to nothing. E.g "Benutzeroberflächen" is displayed as "oberflächen".

I also expected a problem with Realnames at the recent changes page: The usernames are not displayed with their realnames.
