Which confirms there's a bug somewhere.

Which is something that should never happen no matter what. The very
fact that this can happen is _the_ bug (unless, of course, one manually
runs a command to purposefully create that situation, with some kind of
--force option or after answering "yes" to a warning prompt).

Assuming that your diagnosis is correct, that is. Of which I am not
completely sure, given that you have a history of negating facts (as in
"I haven't seen anyone report this on a fresh install").

Title:
  Ubuntu 14.04 Update breaks grub, resulting in "error: symbol
  'grub_term_highlight_color' not found"

Status in “grub2” package in Ubuntu:
  Triaged

Bug description:
  The update from 13.10 to 14.04 via update-manager broke grub for me,
  which resulted in the grub error:

  "symbol 'grub_term_highlight_color' not found"

  on startup.

  To fix the problem I had to boot to my persisting Ubuntu installation
  (e.g. using Super Grub Disk) and had to reinstall grub on my boot
  partition: "sudo grub-install --recheck /dev/sdx"
