Ah you use LVM.
There's a known problem with it's circular metadata which isn't yet
fixed  upstream but there's a patch floating around which solves this.
Maybe that's your problem.
I just tried now a mdraid md2 which goes over mdraid md1 and md0 and
this didn't lead to a segfault in grub-probe.

Here you find the patch and intructions how to compile it:

If this still doestn't solve your problem then we need a GDB backtrace.
Instructions for this are in same report.
Maybe this is even related to it.
