Bug#567728: grub-common: update-grub fails to generate a valid entry for my windows 7 installation

[Matthias Berndt]

Package: grub-common
Version: 1.98~20100128-1
Severity: important

Hi,

the latest grub2 update broke the windows 7 entry. When i run update-grub, i get the following output:

Generating grub.cfg ...
Found background image: moreblue-orbit-grub.png
Found linux image: /boot/vmlinuz-2.6.32-trunk-686
Found initrd image: /boot/initrd.img-2.6.32-trunk-686
Found memtest86+ image: /boot/memtest86+_multiboot.bin
Found Windows 7 (loader) on /dev/hda1
/usr/sbin/grub-probe: error: unknown filesystem.
done

When i run /etc/grub.d/30_os-prober i get 

Found Windows 7 (loader) on /dev/hda1
menuentry "Windows 7 (loader) (on /dev/hda1)" {
/usr/sbin/grub-probe: error: unknown filesystem.
        chainloader +1
}

As can be seen, a line specifying the root device (i. e. set root=(hd0,1)) is missing. If i add it by hand, everything works fine.
