With Empathy running, I run 'empathy-accounts' from the terminal (because the accounts dialog cannot be accessed from within Empathy or from the Unity menu bar; I think that's a separate bug), I create a Facebook account and enter my username and password.
When I click 'Apply', on the terminal appears:
** (empathy-accounts:4659): CRITICAL **: identity_store_credentials_reply: assertion `priv->identity_info == NULL' failed
After trying to connect for about a minute, the message "Disconnected — Authentication failed" appears in the accounts dialog.

Also, within Empathy the notification "Facebook account requires authorisation" appears. The message is not localized to en_CA, and the icon that appears is the stock 'missing' icon.
