grub crashes setting up a EXT2_GOOD_OLD_REV filesystem

Binary package hint: grub

grub 0.97-29ubuntu21, on Ubuntu 8.04.2

To reproduce this bug, create an empty filesystem with genext2fs and install grub onto it. In this test there isn't any grub config so the grub utility should just say "file not found", but instead it crashes.

$ genext2fs -b 2048 test.img
$ grub --batch

         completions of a device/filename. ]

This has been corrected in http://bugs.gentoo.org/show_bug.cgi?id=220687

On line debian/patches/ext3_256byte_inode.diff, instead of

+#define EXT2_INODE_SIZE(s) (s->s_inode_size)

It should be:

+#define EXT2_GOOD_OLD_REV 0 /* The good old (original) format */
+#define EXT2_DYNAMIC_REV 1 /* V2 format w/ dynamic inode sizes */
+#define EXT2_GOOD_OLD_INODE_SIZE 128
+#define EXT2_INODE_SIZE(s) (((s)->s_rev_level == EXT2_GOOD_OLD_REV) ? \
+ EXT2_GOOD_OLD_INODE_SIZE : \
+ (s)->s_inode_size)

I'm not sure if the patch can just be edited. I presume the patch would then have incorrect line numbers.
