...after some more trying. This test fails in the same way:

"""
  >>> import grok
  >>> from zope import component
  >>> from grok.ftests.utility.local import *
  >>> grok.grok('grok.ftests.utility.factoryutility')
"""

import grok

class ObjectFactory(object):
    grok.implements('IFactory')
    grok.name('objectfactory')

    def __call__(self):
        return object()

grok.global_utility(ObjectFactory, direct=True)

And this test does *not* fail:

"""
  >>> import grok
  >>> from zope import component
  >>> from grok.ftests.utility.local import *
  >>> grok.grok('grok.ftests.utility.factoryutility')
"""

import grok

class ObjectFactory(object):
    grok.name('objectfactory')

    def __call__(self):
        return object()

grok.global_utility(ObjectFactory, provides=IFactory, direct=True)
