I'm sorry, but it's really the best I could do. I'm trying hard *not*
to file duplicate reports, but in this case I overlooked a significant
difference between the two problems.

Press return to continue.
If I try the command
/usr/sbin/grub-probe --device /dev/mapper/lvm-root \
--target=abstraction
as root I get a segmentation fault.
I can't get a meaningful backtrace out of it, even though I have
libc6-debug installed. valgrind reports an invalid read in libc, which
looks like it happens in grub-probe, but I have no debugging symbols
for it.
