      STEPS TO REPRODUCE

      1. Login as Admin
      2. Go to Administer Wiki > Content > Localization and set Multilingual to 'Yes' with Supported Languages 'EN, FR'
      3. Create a page with a translation (original EN + translation FR)
      4. Delete the original page (which will delete the translation too)
      5. Go to Page Index > Deleted Pages
