I just noticed, that there is a "Translations" folder now with the latest svn. So I went ahead and made a german translation.
I got it attached.
By the way, I think the english translation has some danish stuff in there and got messed up.
OK, for all of you wondering why that new localization is not working (latest svn) you need to put the skintranslations plugin (delivered with svn) into your process plugin folder.
