Sorry for the late reply...I've got no excuse
Copy/Paste was not designed to work between files, only within the same file. Please file an Enhancement Request bug here.
The reason you're getting that exception is probably because the Process being referenced by the Participant being copied has disappeared somehow. Since it is only being referenced by the Participant, the Process definition and all of its contents still remain in the source file. If the source file is deleted or the Process in the source file is deleted, the references can no longer be resolved and your target file is corrupt.
This problem is not as easy as it sounds. Not only do you need to copy the Participant, but also the Process it references, and all of its contents (i.e. Lanes, Activities, Events, Gateways, SequenceFlows etc.) You also need to copy the BPMNDI elements involved, all of the BPMNShape and BPMNEdge elements, and paste them into the same BPMNPlane as your Collaboration. You also need to make sure that the IDs of the elements you copied do not collide with IDs of existing elements in the target Collaboration. Your best bet is to use an XML editor to accomplish this.
If this is something you're going to need to do more than once, you could possibly write java code. The problem is that each copied element needs to be "cloned", since moving the element from one file to another simply creates a reference from the target file to the source, as you've already discovered.
