Comment 12 for bug 449679

I've bumped the priority of grub2 source and the grub-{pc,common} binaries in the karmic archive to 'optional'. That will take care of this problem for any users upgradng from the network, but this problem may still affect anyone upgrading from a local karmic alternate CD, since those are not expected to be regenerated between now and release.

It's appropriate to get the priority as listed in the source package updated, but this is not at all urgent.
