Title:
  grub-setup segfault

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  There was a machine with one disk, one md0 raid1 root partition.
  Disk partitioned in normal, MBR way.

  The secondary md1 partition is a PV for an unused VG.

  I put a new disk and synchronized raid1 data into it.

  Then:

  $ grub-install  /dev/md0            
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  Segmentation fault (core dumped)

  or rather:

  $ /usr/sbin/grub-setup --directory=/boot/grub --device-map=/boot/grub/device.map /dev/md0  
  error: unknown LVM metadata header.
  zsh: segmentation fault (core dumped)  /usr/sbin/grub-setup --directory=/boot/grub --device-map=/boot/grub/device.ma

  $ grub-install /dev/sda and sdb works fine.

  In case it's necessary, I can remove the VG, but it's obviously cannot
  be a valid fix.
