[XeTeX] Strange hyphenation with polyglossia in French

Hello all,
I'd never had (or noticed) that problem before, so I don't know if it's a new thing or something I do that does not comply. The problem is simple, hyphenation occurs between an apostrophe and the word it follows : l'information in my case becomes l'-information.
I'm using the latest updated 2010 MacTeX.
I didn't find anything helpful in my searches online, so, since I cannot change the text (it's an article from Le Monde)  what can I do?

In making the small version I include here, I also noticed something surprising: the hyphenation changed depending on the length of the text I cut *after*. Leaving one sentence or two did not give the same results. Cutting immediately after the sentence gave the correct l'in-formation and  l'infor-mation was what I got when cutting before De toute part.

I also noticed that including or not
changes things quite a bit while \frenchspacing did nothing obvious. I thought it would deal with spaces around the guillemets etc. but no. I'm wondering why I bothered including it. Is that a benefit from polyglossia?

Jamais le concept de « mal-info » n'a été aussi adapté pour décrire la transformation de notre rapport à l'information. Avec la crise, le « bruit de fond » de l'information a monté, au point que notre écosystème médiatique s'en est trouvé altéré. Car il s'agit aussi d'une crise de l'information. Certes toute crise voit la circulation de celle-ci s'accélérer, mais aujourd'hui l'horizon que doit surveiller l'honnête homme qui cherche à s'informer est devenu mondial. De toute part, il est bombardé de nouvelles plus brèves et moins compréhensibles les unes que les autres. Son entendement est submergé.
