S&D 0.8.13 doesn't work with LinguaPlone 3

[Marlon Richert]

I get the following when trying to access http://example.com:8080/Plone/manage_workspace after doing a successful buildout with both collective.dancing 0.8.13 and Products.LinguaPlone 3.0c3 in my buildout.cfg, and with LinguaPlone already installed in my Plone site (but not S&D):

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))

hmm, never had problems using LinguaPlone with S&D, can you provide a full traceback?
