Ok, I added  the transaction... still bangs, the full traceback is at 
the end...
Note that if I don't add Indexes, zope3 starts, full of articles. But 
when I add the index via TTW and reindex, the articles that I added in 
the install.py script aren't indexed (so the IIntIds was not active 
during the install.py), BUT if I add further articles TTW, the added are 
  indexed...

I really donno what/where to dig ;-(


     # app is a ISite...
     assert ISite.providedBy(app)

     # get the sitemanager
     sitemanager = app.getSiteManager()
     default = sitemanager['default']

     # add an intids
     intids = IntIds()
     default['intids'] = intids
     intids_reg = UtilityRegistration('', IIntIds, intids)
     default.registrationManager.addRegistration(intids_reg)
     intids_reg.status = ActiveStatus

     # add a catalog
     catalog = Catalog()
     default['catalog'] = catalog
     catalog_reg = UtilityRegistration('', ICatalog, catalog)
     default.registrationManager.addRegistration(catalog_reg)
     catalog_reg.status = ActiveStatus

     # Commit the transaction before adding the indexes
     transaction.commit()

     catalog['title'] = FieldIndex('title', IArticle)
