I was about to report a similar bug for grub as the move to UUID everywhere currently prevents my edgy system from booting (I can boot if I put back the old "root=/dev/mapper/...." argument in grub). I am marking this as also affecting grub, for the record.
On the other hand, I find UUID better than labels or lvm volume names as they are more likely to be uniq. A while ago I put a friend's hard drive in my computer to get its data back, we where both using LVM with identical volume names, which was a bit problematic (I don't remember the details though). UUIDS might help in this area, but pushing the user to choose non-clashing LVM names might be enough.
I have mixed feelings about this.
