Bug#487565: grub-pc: Grub2 fails to boot after upgrade from Grub Legacy

[Jeff Grossman]

Package: grub-pc
Version: 1.96+20080621-1
Severity: grave
Justification: renders package unusable

I upgraded my grub legacy system to grub2.  After installing I rebooted 
the machine and selected grub2 (I am using the chainloading method right 
now) and received the following error:

invalid file '(md0)/boot/grub//normal.mod'

and it put in grub rescue mode.  Notice the two "/" after grub.  That is 
what was displayed on the screen.  I cannot find where that line exists.
