The attachment seems to have been mangled: when I looked at it here I only got question marks in the translations. So unless the mangling only happened here, that would be one reason why the patch has not been applied.
Also, although the translation comes from Transifex.com, it looks like you're the only author behind the changes in that patch, i.e. there's presumably no copyright attribution issue. That may be worth noting in the patch submission.
Could you resubmit your patch?
