Title:
  grub-setup crashed with SIGSEGV in __libc_start_main()

Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  I was trying to install Grub2 to the sda mbr after grub failed to
  install with ubiquity installing the Oneiric daily image downloaded
  10-10-11. I used the command "grub-install --root-device=/mnt/@/
  /dev/sda". I had a btrfs filesystem mounted at /mnt, with the main
  subvolume '@' and the /home subvolume '@home'.
