/boot/grub might be a mount point for a small storage device, and so big
stuff like fonts might not fit (I got reports of this happening in Debian
BTS).

Maybe we have something buried deep in Debian BTS. It might take more time
to find it than to fix the bug, though ;-)
The problem is like: When LVM is based on physical partitions that belong
to a pc or gpt table, "grub-probe -t partmap /some/lvmed/mntpoint" won't work.
