Bug#679214: grub-pc: Grub2 fails to boot from a degraded mdraid RAID6

Package: grub-pc
Version: 2.00-13
Followup-For: Bug #679214
This bug still exists in grub 2.00 on Debian.
The trigger cause seems to be 'extra' devices in mdraid arrays.
RAID1 > 2
RAID5 > 3
RAID6 > 4
Can anyone else reproduce this with a 6 disk array and / on LVM?
