Warning logged when navigating to original of translated document

When a CMS user translates a document and then navigates back to the original document, the CMS logs a warning.

Steps to reproduce:
1. login to the archetype CMS as admin
2. create a translated root folder with the language 'Dutch'
3. link the Dutch root folder to the existing English root folder
4. Open the 'News/2011/PBS asserts...' document and translate it to Dutch using the language dropdown
5. When the newly created Dutch document shows up, select 'English' from the language dropdown to switch back to the English document

Expected: no warnings in the logs
Actual: the following warning is logged:
