Rails 3.0.3: использование vestal_versions с globalize3

Question

Я пытаюсь добавить vestal_versions (1.2.2) на сайт, который использует globalize3 (0.0.11) для локализации моделей.

Когда я пытаюсь отобразить версию модели следующим образом:

 <% if can?(:edit, Page) then %>
  <div class="edit_link"><%= link_to image_tag("appicons/edit.png", :alt => t(:edit)), edit_page_path(@page) %><br />
  Version <%= @page.version %></div>
<% end %>

Я получил:

Ошибка типа в Viewer#show

Показывает /home/florian/spzwww3/app/views/viewer/show.html.erb, где поднята строка #50:

Не могу посетить Условие

Линия № 50 - это та, @page.version

Отображение версии в консоли работает нормально:

ruby-1.9.2-p0 > p = Page.find(:last)
ruby-1.9.2-p0 > p.version
 => 1 

Любые идеи, что означает условие "Не удается посетить условие"?

Я никогда не видел это сообщение раньше, и Google возвращает только один несвязанный результат для этой фразы.

Заранее спасибо за любые советы.
