This bug was fixed in the package grub2 - 1.99~rc1-6ubuntu1

---------------
grub2 (1.99~rc1-6ubuntu1) natty; urgency=low

  * Resynchronise with Debian.  Remaining changes:
    - Adjust for default Ubuntu boot options ("quiet splash").
    - Default to hiding the menu; holding down Shift at boot will show it.
    - Set a monochromatic theme and an aubergine background for Ubuntu.
    - Apply Ubuntu GRUB Legacy changes to legacy update-grub script: title,
      recovery mode, quiet option, tweak how memtest86+ is displayed, and
      use UUIDs where appropriate.
    - Fix backslash-escaping in merge_debconf_into_conf.
    - Remove "GNU/Linux" from default distributor string.
    - Add crashkernel option.
    - Bypass menu unless other OSes are installed or Shift is pressed.
    - Allow Shift to interrupt 'sleep --interruptible'.
    - Reduce visual clutter in normal mode.
    - Remove verbose messages printed before reading configuration.
    - Suppress kernel/initrd progress messages, except in recovery mode.
    - Handle filesystems loop-mounted on file images.
    - Ignore devices loop-mounted from files in Linux grub.d scripts.
    - Show the boot menu if the previous boot failed.
    - Don't generate device.map during grub-install or grub-mkconfig.
    - Adjust upgrade version checks for Ubuntu.
    - Suppress "GRUB loading" message unless Shift is held down.
    - Adjust versions of grub-doc and grub-legacy-doc conflicts.
    - Fix LVM/RAID probing in the absence of /boot/grub/device.map.
    - Look for .mo files in /usr/share/locale-langpack first.
    - Make sure GRUB_TIMEOUT isn't quoted unnecessarily.
    - Build-depend on qemu-kvm rather than qemu-system for grub-pc tests.
    - Use qemu rather than qemu-system-i386.
    - Add a grub-rescue-efi-amd64 package.
    - On Wubi, don't ask for an install device, but just update wubildr
      using the diverted grub-install.
    - Enable lua from grub-extras.
    - Incorporate the bitop library into lua.
    - Add enum_pci function to grub module in lua.
    - Check hardware support before using gfxpayload=keep.
    - Build part_msdos and vfat into EFI boot images.
    - Put second and subsequent Linux menu entries in a submenu.
    - Preferred resolution detection for VBE.
    - Set vt.handoff=7 for smooth handoff to kernel graphical mode.
    - Build with gcc-4.5 on ppc64.
    - Add apport hook for ProblemType = 'Package'.

grub2 (1.99~rc1-6) unstable; urgency=low

  * Cherry-pick from upstream:
    - Fix crash when extending menu entry line beyond 79 characters (closes:
      #615893).
    - Account for FreeBSD module headers when calculating allocation size.
    - Switch back to framebuffer page zero before loading the kernel
      (thanks, Felix Kuehling).
  * Merge from Ubuntu:
    - If we're upgrading and /boot/grub/core.img doesn't exist, then don't
      ask where to install GRUB, since it probably means we're in some kind
      of specialised environment such as a live USB stick (LP: #591202).
    - Drop the default priority of grub2/linux_cmdline to medium.  We only
      need to ask it if we're upgrading from GRUB Legacy and found an empty
      kopt in menu.lst (LP: #591202).
  * Update branch_embed-sectors.patch, avoiding consuming lots of space and
    time if the first partition is not near the start of the disk (closes:
    #619458, LP: #691569).
