This is the same problem as documented in bug 348393. I know that bug was filed later, but since it already has a diagnosis and the right bug status, I'll mark this one as a duplicate.
(The reason you couldn't duplicate it with 8.04.1 is that the French language pack happens to be on the i386 alternate install CD there; but, for instance, it isn't on the amd64 CD due to lack of space.)
