I've fixed the core dump, but that's not really the problem.  It nows
raises an exception somewhere else.

I don't understand why the "class app.App" line says "<type
'persistence.Persistent'>".  I would expect it to say "<class
'app.App'>".  It looks like I don't have a test for that in zodb.code,
so I'll need to look further.  I'd guess that the patch code is making a
mistake.
