After installing Ubuntu 12.04LTS, I receive the following error whenever I attempt to load the UbuntuOne client:

CredentialsError
DBusException(dbus.String(u'
  Traceback (most recent call last):\n
    File "/usr/lib/python2.7/dist-packages/dbus/service.py", line 707, in _message_cb\n
      retval = candidate_method(self, *args, **keywords)\n
    File "/usr/lib/python2.7/dist-packages/ubuntuone-client/ubuntuone/platform/credentials/linux.py", line 185, in find_credentials\n

      message.append(signature=signature, *args)\n
  ValueError: Unable to guess signature from an empty dict\n
'),)

Ubuntu One is not syncing data, and can't even start without crashing (giving the report copy&pasted above).

Does anybody have any ideas as to how I can remedy this?

Thank you!

Yes, I found that bug and I'm concerned -- that bug is from 2011 and I guess it still isn't resolved? But it only happened immediately after I upgraded to Ubuntu 12.04. I've searched for hours and cannot figure or find a solution. Thanks for suggesting that bug, nonetheless... :-) – Joe Seemiller Apr 29 '12 at 3:43
