F17: /boot/grub2' is not readable by GRUB on boot. Installation is impossible. Aborting.

[Nick Urbanik]

Dear Folks,

I've installed F17 on this machine with yum,
[https://fedoraproject.org/wiki/Upgrading_Fedora_using_yum] and it
seems okay so far, except for this:

$ sudo grub2-install /dev/sda
/usr/share/grub/grub-mkconfig_lib: line 53: 29562 Segmentation fault      (core dumped) "${grub_probe}" -t fs "$path" > /dev/null 2>&1
Path `/boot/grub2' is not readable by GRUB on boot. Installation is impossible. Aborting.

I'm afraid to reboot.
