Thanks for the suggestion Séverin. You can always just put a comment to the contribution, explaining that the contribution should be discarded (rejected). These comments are automatically sent to the language pack maintainers so they will know. I must admit that my time is limited and there seem to be more serious issues with AMOS I would like (and should) work on. In any case, please feel free to submit a feature request into the tracker. Maybe someone can come up with a patch.
