This is likely to be a conflict between changes of \catcode and internal
definitions of xy-pic.

Which error message do you get?

Try \usepackage[frenchb]{babel} and give us the full preamble of your

I am not a user of xy-pic so I don't know if it is or not a known bug. Maybe
you can look at

Et bonne chance!
