I happen to know about this "France problem" because for a while it affected the OCaml distribution (it has now been resolved by some French-specific legal wrangle).
I don't know how this affects the GPL specifically, but you can be pretty sure that if the GPL doesn't contain France-specific French-language legalese to work around it, then it's likely to be revokable whatever the license says. Of course this only affects you if you're in France or have French contributors.
