Consider following scenario:
You install GRUB to both sda and sdb.
Then you do a sudo aptitude upgrade or equivalent. It finds a new GRUB
version and installs it, updating core.img on sda and modules. So
core.img from sda and modules are in sync. But the core.img on sdb isn't
updated and so it gets out of sync with modules.
Another possible reason for such a failure is a mdraid array desync.
Yet, there was a similar report affecting some other users to warant
further investigation. Could you try to do in GRUB shell:
insmod gettext
lang=fr
and tell the result?
