Comment 10 for bug 1170832

The same problem occurs to me on Ubuntu 13.04! I have tried removing-reinstalling empathy, Facebook Accounts Plugin, UOA; I have also deleted any temporary files using BleachBit. Nothing seems to fix the problem...
Furthermore, I noticed that the Unity Menu Tab responsible of displaying Facebook News works fine. The problem is localized to Empathy Messenger when trying to connect to a Facebook account which happens to have 2-Step Verification turned on. Is there any possibility that the Authentication Tokens (when you start Seahorse, you can see two) are mixed up after a while? Each time they are updated, their number is changed (i.e. Ubuntu Web account: id #-#); I imagine that Empathy might be looking for older tokens than the current, because this problem occurs usually after 15 days (the normal time between account re-authorisations).
It's high time someone fixed this bug! I'm bored stumbling upon this particular problem since I installed this last version of Ubuntu; and it's is a pity, because it's far the best Linux Distribution out there!!! :D
Thanks in advance...
