OK, thats definitely Bad. You should always use @PersistenceContext inside a REQUIRES_NEW bean, and get a container-managed PC. The Seam-managed PC is associated with the outer (suspended) tx managed by Seam. You shouldn't associate it with a new one. Its only allowed to be associated with one transaction at a time. I wish there was an easy way for me to detect cases like this, but its actually very difficult, because all I have is a UserTransaction, and no Transaction.
