I get the following when trying to access http://example.com:8080/Plone/manage_workspace when I have both collective.dancing 0.8.13 and Products.LinguaPlone 3.0c3 in my buildout.cfg:

Error Type: TypeError
Error Value: ('object.__new__(SyncedLanguages) is not safe, use Persistence.Persistent.__new__()', <function _reconstructor at 0x2b27f593eb18>, (<class 'Products.LinguaPlone.vocabulary.SyncedLanguages'>, <type 'object'>, None))
