Sorry - my fault :-) I'm using queryUtility all the time. Here's the traceback:

  File "/var/lib/zope3/instance/lib/python/fb/init/tales.py", line 29, in warn
    indicator=zapi.getUtility(IInitIndicator,None)
  File "/ZOPE/zope3/src/zope/component/_api.py", line 207, in getUtility
    raise ComponentLookupError(interface, name)
ComponentLookupError: (<InterfaceClass fb.init.interfaces.IInitIndicator>, None)
