Bug#315339: installation of new lvm2 renders vg unusable

[Igor Belyi]

Package: lvm2
Version: 2.01.12-2
Followup-For: Bug #315339

Installing new lvm2 makes stripped VG unrecognizable.
Downgrading lvm2 back to 2.01.04-5 fixes the problem.

# vgdisplay lvmg
  LV backup: inconsistent LE count 1832 != 3662
  Internal error: LV segments corrupted in backup.
  Volume group "lvmg" doesn't exist    

Attached is the /etc/lvm/backup/lvmg config file for the group.
