That bug is slightly different; it concerns having _more than one_
entry in subclass(es)'s tables refer to the _same_ entry in the
superclass's (which pretty much breaks the analogy with class
inheritance, if you ask me).
My situation is that I have various instances of Document, some of

Hmmm, I seem to have somewhat figured out what's going on.
Using Marc's example, when you instantiate u it's doctype field is set
