Bug#466389: grub-pc: chainloading grub2, size=0x00

[Arthur Marsh]

Package: grub-pc
Version: 1.96+20080601-2
Followup-For: Bug #466389


When I select the following option:

title   Chainload Grub2
root    (hd0,4)
#kernel  /boot/grub/boot.img
kernel /usr/lib/grub/i386-pc/lnxboot.img
savedefault

from my grub-legacy start menu, 

I get the following:

root (hd0,4)

Filesystem type is ext2fs, partition type 0x83

kernel /usr/lib/grub/i386-pc/lnxboot.img

[Linux-bzImage, setup=0x200, size=0x0]

savedefault

[copied by hand] and then nothing, requiring a control-alt-delete to 
restart.

The lnxboot.img is apparently being read but what ever is supposed to 
happen next fails.
