If I remember your original message properly, the error you got from pvcreate 
was that the disk "contained a partition table". This is _not_ the same thing as 
the disk containing one or more partitions; there can very well be an empty 
partition table on the disk. This may not be the problem, but if it is, using

dd if=/dev/zero of=/dev/sda count=20

will wipe out any existing DOS-type partition table (or any other type of table 
that resides at the beginning of the disk). If you've already tried this, then 
I'd say there is definitely a bug happening.
