Title:
  grub-probe crashed with SIGSEGV

Status in grub2 package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: grub2

  I updated from Ubuntu 10.04 to Ubuntu 10.10. During the update
  process, there were errors with grub, something like:

  >Generating grub.cfg...
  >Segmentation fault (core dumped)

  After the update process and before rebooting, I tried to update grub
  in a terminal:

  sudo update-grub

  but the same errors occurred. So I manually created the file
  /boot/grub/device.map with the following content:

  hd0)    /dev/sda

  then I done:

  sudo update-grub

  without any errors. I successfully rebooted, but there was this error
  notification in my systray.
