Package: grub-common
Version: 1.97~beta4-1
Severity: important
grub-setup is segfaulting in its lvm scanning code. This made my system
unbootable. Since even grub-legacy uses grub-probe from grub-common,
getting my system to boot again was quite the ordeal :(
A stack trace of the crash, from a debug-enabled build:

Note: this same stack trace (more or less) also happens in grub-setup, so
one can't even recover a system's bootability by doing the grub-setup bit
manually!
In order to get the system to boot at all, I had to replace grub-probe with
a shell script with hard coded ouptuts for all the queries grub-install and
update-grub make. Not Fun.

Belatedly: this bug should have been fixed in the version above, thanks
to a patch from Dan Merillat that went upstream.
