Bug#586449: unbootable system after grub-pc upgrade (unaligned pointer) locales problem

[Andre Nunes Batista]

Package: grub-pc
Version: 1.98+20100617-1
Severity: grave
Tags: upstream
Justification: renders package unusable


Hi, after the last grub-pc and grub-common update my system was rendered unbootable. 
I originaly thought I had te same problem as described by other people on bug #586143,
however I couldn't solve my problem following the same steps as others. (grub-install and so)

When I try dpkg-reconfigure I get a lot of messages regarding locales unset and the need 
to manually give --modules.
