Comment 7 for bug 1311247

grubenv attached...

loadenv.c (grub source):

          if (e1 > s2)
            {
              /* This might be actually valid, but it is unbelievable that
                 any filesystem makes such a silly allocation. */
              return grub_error (GRUB_ERR_BAD_FS, "malformed file");
            }

I have many Linux and other test partition
:-)

My fdisk -l output:
