Functional test support for these was added with the latest release
but only for API driven tests. Can you try adding interactor="api" to
your test cases?

Yes it is a corner case I personally had not tested. Are you are
running something later than the latest dist but not the latest
central? It seems like yes. Because I believe Dan has fixed the bug
that produces the particular stack trace you are seeing last week - he
has probably fixed the other problems you mentioned also? Can you
upgrade and let me know, if not let me know and I can take a look a
closer look.
