AFAIK, send -c does require a parent, but if there's clones and no parent given, it will try to pick its own from the list of clones given. Which explains the error complaining about being unable to find a parent, when given only clone sources that (based on your reproducer) had nothing in common with the snapshots listed as clones. -- Duncan - List replies preferred.
