[Product-Developers] Problem with roles and plone.app.testing

[Noe Nieto]

On one of my tests I'm trying to create some folders.  This is the layer
class:

# ... adequate python imports

class CatalogosFixture(PloneSandboxLayer):
    defaultBases = (PLONE_FIXTURE,)

    def setUpZope(self, app, configurationContext):
        # Load ZCML for product dependencies
        .....

    def setUpPloneSite(self, portal):
        #Install products and dependencies
        self.applyProfile(portal, 'plone.app.dexterity:default')
        self.applyProfile(portal,'holokinesislibros.contenttypes:default')
        self.applyProfile(portal,'holokinesislibros.catalogos:default')

        #Create a layout for testing
        from plone.app.testing import setRoles
        from plone.app.testing import TEST_USER_NAME
        setRoles(portal, TEST_USER_NAME, ['Manager'])

        portal.invokeFactory('Folder', 'catalogo-general', title=u'Catalogo
General')
        portal.invokeFactory('Folder', 'libros', title=u'Libros')
        portal.invokeFactory('Folder', 'videos', title=u'Videos')
        portal.invokeFactory('Folder', 'audios', title=u'Audios')

    def tearDownZope(self, app):
        ...

While running one DocTest with this fixture I get this traceback:

I'm stuck here, What am I doing wrong?
