Hi,
try this:

from zope.schema.vocabulary import SimpleVocabulary, SimpleTerm


def vocabulary(*terms):
    """
    Gibt ein Vokabulary zurück
    """
    return SimpleVocabulary([SimpleTerm(value, token, title) for value,
token, title in terms])


class MyInterface(zope.Interface):

  
    q_type = Choice(
        title = u"foobar",
        description = "",
        vocabulary = vocabulary(
      ('1', 'Fehler', u'Fehler'),
            ('2', 'Aenderung', u'Änderung'),),
     
        required = False,
    )
