merge 593652 594518
severity 593652 grave
found 593652 1.98+20100720-1

thanks

593652 is regression.
grub-probe from 1.98+20100710-1 (taken from snapshot.debian.org)
does not segfault. grub-probe is not enought: with only this binary
or the whole grub-common from 1.98+20100710-1 then grub-setup segfault.
Installing both grub-common and grub-pc 1.98+20100710-1 makes grub
working again on my system.
