Even though everyone in this bug log seems to be doing this, it's
unlikely actually to be the best idea, and it certainly won't help to
resolve this bug.  Try upgrading again; record the output from the
upgrade, and send it to me; and if you see the problem again, get the
value of grub-pc/install_devices using 'debconf-show grub-pc', and try
running 'grub-install /dev/sda' (replacing /dev/sda with the value of
grub-pc/install_devices') to see if that fixes it, as others have
reported.

What I really need is a way to replicate this.  I've tried LVM and
LVM+crypto installs in a virtual machine, upgraded to the latest version
of grub-common and grub-pc, and so far have been unable to recreate
this.

... probably because downgrading to 1.98-1 loses a bunch of other fixes
that are relevant for LVM ...
