Comment 5 for bug 476930

I wonder if this is related to gnome keyring. Here is the traceback from ~/.cache/ubuntuone/log/syncdaemon.log:

NoAccessToken: No access token found.
2009-11-12 12:06:19,400 - ubuntuone.SyncDaemon.DBus - ERROR - Can't get the auth token
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/dbus_interface.py", line 1073, in connect
    access_token = self.main.get_access_token()
  File "/usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/main.py", line 299, in get_access_token
    return self.oauth_client.get_access_token()
  File "/usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/main.py", line 339, in get_access_token
    raise NoAccessToken("No access token found.")
NoAccessToken: No access token found.

Looking at /usr/lib/python2.6/dist-packages/ubuntuone/syncdaemon/main.py it seems it throws that exception when trying to access the token through gnome-keyring - lines 327 - 432.
