I can confirm this bug report. I also have root RAID 1 (and it's an old RAID volume created August 12th, 2005 so probably on an etch system). Upgrading to grub-pc 2.00-14 rendered my system unbootable (in the grub recovery console, my disks showed up but all their partitions were missing). Downgrading back to 1.99-27+deb7u1 allowed me to boot once more. If there is any further information I can provide to help, just let me know.
