Package: grub-common
Followup-For: Bug #593652


When doing kernel security updates, aptitude says update-grub failed with error 139.
Checking other bug reports lead me to try grub-probe -vv -d /dev/system/root -t abstraction
which works fine on my many logical volumes until it get to my root volume (/dev/system/root),
where it segfaults.  Thought there might be some data needing to be flushed, so ran sync.  No dice.

Tried updating grub, but couldn't finish because the other kernels haven't finished configuring.
The root filesystem (ext3) hadn't been checked in many years, but I'm not in a position to reboot. 

So I created an lvm snapshot and ran fsck on the snapshot; it came up clean.
Then I ran grub-probe, and it finished WITHOUT segfaulting (go fig).
Ran update-grub, it finished without error.
Ran aptitude install, finished configuring the kernels and updated grub without issue.
