[bug #44199] grub2-mkconfig: /usr/share/grub/grub-mkconfig_lib: line 56: 26488 Segmentation fault "${grub_probe}" -t fs "$path"

[Tumaykin Ilya]

Follow-up Comment #3, bug #44199 (project grub):

I've added a couple of debug prints before the line that causes the problem:
  grub_warn "$path"
  grub_warn "${grub_probe} -t fs $path 2>&1"
  grub_warn "`"${grub_probe}" -t fs "$path" 2>&1`"

Here's how output of grub2-mkconfig looks now:

And I've attached core file for `/usr/sbin/grub2-probe -t fs
/usr/share/grub/unicode.pf2` command.
