The reason offered to explain this issue was: http://www.facebook.com/help/?page=416 → Bugs and known problems → I don’t have a preview for my link.
I haven't investigated in details, but it may be fixable on our end.
Commons pages are indeed missing those three recommended meta tags, but I am not entirely sure that providing them would solve the problem (it's worth a try though).
Thanks, Bence
