According to your oauth-login.log, you did have an Ubuntu One token as per:
2011-01-07 13:34:24,058:58.7830543518 - ubuntu_sso.main - INFO - keyring_get_credentials: app_name "Ubuntu One", resulting credentials is not None? True 2011-01-07 13:34:24,059:59.051990509 - ubuntu_sso.main - INFO - SSOCredentials: emitting CredentialsFound with app_name "Ubuntu One" So, now that you have cleared all your tokens, could you please run in a terminal: u1sdtool -c after syncdaemon starts (that can take a while), the sso GTK UI will be raised for you to login. Please try to login and if you can't, attach the sso log file (under .cache/sso/).
