Parted crash on GPT filesystem access
Description
==============
Attempting to list elements of Fake Raid causes a crash in parted
Environment:
Hardware:
Asus P6T WS / i7 950 / 12GB ddr3
1 WD 160 HDD SATA
dual boot winsux7 / kubuntu 10.01
5 WD 1TB HDD SATA Fake RAID5
fake raid enable in bios
dm-0 = NTFS
OS:
kubuntu 10.10 alternate disk install
data disk array dm-0 (4TB) is NTFS GPT and was formated in winsux7
otherwise completely clean install
Repro:
==============
attempt to list the partions
print list

Observed
=================
parted crashes
Expected
=================
parted should list sda[1-4] and raid5 array dm-0
Additional Information
======================
parted releast version: (2.3)
error message:
Assertion (last_usable <= disk->dev->length) at ../../../libparted/labels/gpt.c:934 in
function _parse_header() failed.

Error: The backup GPT table is not at the end of the disk, as it should be. This might
mean that another operating system believes the disk is smaller. Fix, by moving the backup
to the end (and removing the old backup)?
parted: invalid token: unit
Fix/Ignore/Cancel? Fix
Warning: Not all of the space available to /dev/dm-0 appears to be used, you can fix the
GPT to use all of the space (an extra 1024 blocks) or continue with the current setting?
Fix/Ignore? Fix
