When I attempt to copy/paste or import a Plone site where I've created a single
member of a remember-derived type I get the following assertion error (relevant
code also included below). When I change the offending line
assert len(members) == 1
to
assert len(members) >= 1
reflecting the possibility of more than one result in the query, everything
works fine and the cloned member works fine, retains proper ownership, etc.
Clearly, this isn't a real fix. Any ideas on why this happens and a proper way
to deal with it. Thanks.
