That's actually because 678227 is what made debian-boot consider the
issue quoted above "already reported" (see #684954).

I haven't seen that with squeeze: when I run apt-get update, only the
Translation file for the current locale gets downloaded.

I don't see how that should make apt-get download all languages.

Then don't drop it in the LANG=C case, but do drop it in the LANG!=C
case.

<sarcastic too>There is no reason to download all languages unless you
target the very few people who can speak all languages the descriptions
have been translated to.</sarcastic too>

82M clearly hurts. Really. That's like 15% of the installation size!
