with version ids of en:Oberon an error message is provided in de: http://de.wikipedia.org/?title=Oberon&diff=26851661&oldid=11834839 though http://de.wikipedia.org/?title=Oberon&oldid=11834839 and http://en.wikipedia.org/?title=Oberon&diff=9748699&oldid=4848495 present no error message
You're requesting a diff against a revision that doesn't exist (perhaps was deleted): http://de.wikipedia.org/?title=Oberon&oldid=26851661 So, it's not surprising that it shows an error diffing against it. Resolving INVALID.
