I'm getting another exception in NamedObjId that looks related. This one can be reproduced by opening demos/getting-started/06-WebServicesAndDataTransformation.xml, double clicking on Web Service Actor, then changing the method name. (Make sure your WebService actor source is updated).

Fixed. There were two bugs: dereferencing a null container, and sometimes the referral list attribute was being created without a name.
