I *think* what you are running into here is the difference between
an context-wrapped object and the unwrapped object.  I think __dict__
gets you the latter, but self.dbTest calls __getattr__ and the Zope
hook for that returns a wrapped object.  The wrapped object can
use acquisition to find the db connection, the unwrapped object can't.

As you found, getattr is the way to do what you want.
