- Without a mo-file loaded for the combination of domain/locale,

  ``pyramid.i18n.Localizer.pluralize`` run using that domain/locale
  combination raised an inscrutable "translations object has no attr 'plural'
  error.  Now, instead it "works" (it uses a germanic pluralization by
  default).  This is not the "right" thing really (it's nonsensical to try to
  pluralize something without translations for that locale/domain available),
  but it matches the behavior of ``pyramid.i18n.Localizer.translate`` so it's
  at least consistent; see https://github.com/Pylons/pyramid/issues/235.

Closes #235.
