title: Error when importing a zexp site that uses LinguaPlone
body: <p>I'm migrating a site from one zope instance to other using the import export tool. The site is using LinguaPlone (Products.LinguaPlone = 4.1.2). Both zope instances are identical because I use buildout and I have picked all eggs. But when migrating it shows the error:</p>
  
  <pre><code>Error Type: AttributeError
  Error Value: 'NoneType' object has no attribute 'getTranslations'
  </code></pre>
  
  <p>I suppose that its the same error that was documented in <a href="http://plone.org/products/linguaplone/issues/241" rel="nofollow">http://plone.org/products/linguaplone/issues/241</a>. How can I fix the site before migrating to the other zope instance?</p>
  
  <p>The complete traceback:</p>
