Bug#502333: grub-pc: Search uuid in LVM crashes the bootloader

[Harald Braumann]

Package: grub-pc
Version: 1.96+20080724-10
Severity: important

The stanza created by 00_header makes the bootloader crash. There is no 
output by grub whatsoever,
the machine reboots immediately.

If I remove this stanza and then enter those commands at the grub cmdline 
one by one, 
the crash occurs in the "search --fs-uuid ..." line. But search only 
crashes for LVM. 
If I don't insmod lvm, the search command just prints some not-found 
message, which 
is expected, but doesn't produce a crash.
