That would be important though in this case.

The crash could be completely unrelated to grub2 and possibly an issue with
your hardware. And if your machine crashes while dpkg is configuring packages,
it is virtually inevitable not to end up with half-broken packages.

Could be an issue with your power supply maybe.

Reproducible in what way? Did the system crash-reboot once more when you tried
to run "dpkg --configure -a"?

I'm currently a bit reluctant to blame grub2 here. This should really be
tested with a fresh installation to try to reproduce it. It's unlikely
to be a bug if we cannot reproduce it.

The log just indicates the fallout from the crash and is something to be
expected. The actual question is why your machine crashed while dpkg
was configuring packages and if it's actually reproducible.
