ubuntuone-syncdaemon NoAccessToken exception when trying to connect

[Seth Forshee]

When I attempt to connect a machine running Precise to an existing Ubuntu One accoung from the Ubuntu One Control Panel, it consistently fails. I get the message "The process did not finish successfully" in the connect dialog followed by a "There was a problem while retrieving the cred" in the control panel window (presumably the message is cut off). The following appears in ~/.cache/ubuntuone/log/syncdaemon-exceptions.log:

2012-01-02 13:53:46,113 - twisted - ERROR - Unhandled error in Deferred:

    raise NoAccessToken("got empty credentials.")
ubuntuone.syncdaemon.interaction_interfaces.NoAccessToken: got empty credentials.

Despite this, the machine shows up in my devices list when viewed on another machine or via the web interface. I am not behind a proxy, and attempting to connect to the same account from another machine running Oneiric is successful.
