Hi,

While using update-grub in the kernel update, an error 130 was reported.
It appears that there is a segfault in grub-probe.

System is X86_64.
/boot is ext3 over a raid1.
The other parts of the system are xfs over lvm over raid1.

I've got older versions to test.
These version works on the system:
1.96+20080413-1
1.96+20080426-1
1.96+20080429-1

These don't:
1.96+20080724-7
1.96+20080724-8

But 1.96+20080724-7 has been updated on the system on august, 11th without any
problem since this update.

Regards

Jean-Luc
