I tried running pvdata -U on one of my LVM servers and it segfaulted
(LVM driver version 0.9.1_beta6). Check out the UUIDs. Everything is
working OK but I wonder if this is a serious problem or not? This is a
single physical volume LVM running on top of hardware RAID 5.

Output just tells you, that no UUIDs have been created dynamically so far.
If you create/remove a dummy LV, they should be there...

No, it is not. Just try the lvcreate/lvremove pair on a small (-l 1) dummy LV.

I created and them removed a small LV and now the UUIDs look more
familiar. :-) Thanks.
