I have similar issue on Ubuntu 12.04 when running an "apt-get dist-upgrade"...
At some point iI get an output very similar to the reproduced:
root@dcmilphlum173:~# grub-mkconfig -o /boot/grub/grub.cfg
Generating grub.cfg ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

The below 4 errors do not occur without the 2 snapshots that I created before running "apt-get dist-upgrade".
Could this be related to the above issue?
I see that the issue from this thread was solved in grub2 (2.02~beta2-9), but the latest version available to precise is the one I have (see below)
root@dcmilphlum173:~# dpkg -l |grep grub
ii grub-common 1.99-21ubuntu3.19 GRand Unified Bootloader (common files)
ii grub-gfxpayload-lists 0.6 GRUB gfxpayload blacklist
ii grub-pc 1.99-21ubuntu3.19 GRand Unified Bootloader, version 2 (PC/BIOS version)
ii grub-pc-bin 1.99-21ubuntu3.19 GRand Unified Bootloader, version 2 (PC/BIOS binaries)
ii grub2-common 1.99-21ubuntu3.19 GRand Unified Bootloader (common files for version 2)
I currently haven't seen any crash or boot failure because of these issues yet, but still I'd like to solve or get around this issue...
