Make sure you get a boarding pass for your connection in Paris. Be persistent here in the States, telling them you'll need it in Paris. Even if they can give you one showing the seat unassigned, that would be good. Otherwise, the retards in Paris will make you go through immigration and customs as if you're staying in France, then go back through the ticket counter and recheck in there.
Don't know what the malfunction is in Paris, but I've flown through there several times and they make me do it every time. All over the world, elsewhere, you get off your plane, follow the signs for connecting flights, and go to your next gate. Paris won't let you do that without a boarding pass for your next flight.
As my buddy says of France: "The French copy no one, and no one copies the French..."
