It looks like the following *should* fix things for you (this from Patrick):

 o Grab the latest CVS code for LVM.
 o Create a very small LV (or extend an existing one) to force a meta-data
   update.
 o The UUIDs should be cleaned up

If this is not possible with your setup, or does not work for you, let me
know and we'll see what else we can do to fix the problem.
