Details:

After playing with custom fonts on the grub menu I've noticed that it doesn't
load the boot menu and also doesn't respond to keyboard actions. The problem
occurs when there's not enough space for rendering the boot menu using the
given font.

Example:
Ubuntu 13.04 (12.04 is affected too, I didn't try other distributions)
Resolution: 640x480
Font: DejaVu Sans Book 18
Generated by: grub-mkfont --output='/boot/grub/unicode.pf2' --size='18'
'/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf'

The problem is, that a user cannot try the chosen font without rebooting.
However if the the grub menu doesn't load then, the user has to use a live cd
to fix this.

I think this behavior should be changed so that it falls back to default font
in this case.
