grub error "superfluous RAID member" on update-grub

Question

My system (wheezy/sid: 2.6.32-5-amd64 #1 SMP x86_64 GNU/Linux) is running fine - I'm just wondering what some messages mean. I have two mdraid arrays running up on my system. Here's cat /proc/mdstat:

Personalities : [raid1] [raid6] [raid5] [raid4] 
md1 : active (auto-read-only) raid5 sda3[0] sdc3[3] sdb3[1]
      823103488 blocks super 1.2 level 5, 512k chunk, algorithm 2 [3/3] [UUU]

md0 : active raid1 sda2[0] sdc2[2](S) sdb2[1]
      72628769 blocks super 1.2 [2/2] [UU]

I use /dev/md0 as / and /dev/md1 as /home. Whenever update-grup is running - or while grub comes up, I receive the error: error: superfluous RAID member (2 found)..

To understand why I'd like to remove this, have a look at the result of update-grub:

error: superfluous RAID member (2 found).
error: superfluous RAID member (2 found).

How can I get rid of these messages?

Solution

This is a bug on the update-grub script. After what is said in the Debian bug report, a patch has been applied upstream so it should be fixed in the Debian package at some time.
