I somewhat missed it - cubic started to work without much errors (the
catalog simply stopped working)

After fixing things/ adding includes, I ran into an old issue again (I
have clean Zope3 svn checkout at this moment, no additional
hacks/workarounds anymore):

  File "/home/ivo/Projects/Zope3/Zope3-svn/src/zope/app/security/adapter.py",
line 88, in __call__    adapter = self.factory(*args)
  File "/home/ivo/Projects/Zope3/Zope3-svn/src/zope/app/keyreference/persistent.py",
line 41, in __init__
    raise zope.app.keyreference.interfaces.NotYet(object)
NotYet: <zope.app.workflow.stateful.definition.State object at 0xb3bd076c>

The IntId utility can't handle these exceptions. The following diff
fixes things (for me, at least)
