NAT & Multilingual nodes

Hi guys!
First of all thanks for the great module!
I am facing a problem which probably can easily solved by tweaking somewhere. I am creating nodes on a content type that get mapped to a taxonomy vocabulary correctly. Unfortunatly my site is using 2 languages, so for each node I have the translation. Nevertheless the title is the same for both translations (it's an artists database and each node has the artist name as title and the artist bio as content) so I end up with a vocabulary with all terms appearing twice. Is there a way to instruct NAT to avoid this?

Hope the issue is clear... let me know if you require any further info's.

Thanks!
Andrea
