Did a test with grub2-probe and it gives same Segmentation fault 
on nfts partitions. Note book had 9 partitions.

for a in $(cat /proc/partitions | grep sda. | cut -b26-40); do echo -n 
/dev/$a" " ; grub2-probe -d /dev/$a; done
/dev/sda1 Segmentation fault (core dumped)
/dev/sda2 Segmentation fault (core dumped)
/dev/sda3 Segmentation fault (core dumped)
/dev/sda4 grub2-probe: error: cannot find a GRUB drive for 
/dev/sda4.  Check your device.map.
/dev/sda5 ext2
/dev/sda6 grub2-probe: error: ../grub-core/kern/fs.c:123:unknown 
filesystem.
/dev/sda7 ext2
/dev/sda8 ext2
/dev/sda9 ext2

Also, noticed /etc/filesystems and /proc/filesystems don't have ntfs??
