Comment 5 for bug 417664

I have the same problem as "ramses" and "KD" . I'm not behind a proxy. The page that allows me to "Add This Computer" (point 4 in the installation guide) never appeared.

When I go to Anwendungen (applications)->Internet->Ubuntu One the client seems to start. At least the Ubuntu One icon appears in the system tray. It says "Updating files..." when I hold the mouse over the icon. But it has a small white cross on red background on it.

I had a look at other bug reports and tried

u1sync --authorize

which hangs after the following error message:

Traceback (most recent call last):
  File "/var/lib/python-support/python2.6/dbus/connection.py", line 578, in msg_reply_handler
    reply_handler(*message.get_args_list(**get_args_opts))

    parameters['oauth_token'] = token.key
AttributeError: 'NoneType' object has no attribute 'key'

I also tried to remove the Ubunutu One key, as was suggested in other bug reports, but I only found WLAN keys in may keyring.
