There are two ways to fix this:

1) comment out the UUID checking in pv_read_all_pv_of_vg(), recompile.
2) apply the UUID patch I posted to the list a few hours ago, recompile
   and re-run vgcfgrestore.  This patch will force creation of new UUIDs
   for all PVs which are missing them, and it will do it properly so
   that they are stored on all disks.
