The system here with the bug is a lucid system.
It has been initially installed with ubuntu in 2005 and migrated to lucid in several updates ;-)

The mentioned bug has been shown up in 2011.

1st I checked that '/usr/sbin/grub-probe --device /dev/md1 --target=drive' doesn't rise an error message.

I have installed manually the following packages:

dpkg -i grub-common_1.99~rc1-13ubuntu3_amd64.deb grub-gfxpayload-lists_0.2_amd64.deb grub-pc_1.99~rc1-13ubuntu3_amd64.deb

The problem doesn't appears any more.

So please update also in lucid
grub2 1.98 --> 1.99~20101126-1ubuntu1 (or newer)
