Comment 2 for bug 674400

Same here:
$ u1sdtool --status

Oops, an error ocurred:
Traceback (most recent call last):
Failure: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Additionally, nautilus doesn't seem to know about ubuntu-one and won't give me the ability to sync folders. The folders I managed to share on other machines are not properly synched either. Only some partial folders and files.

Funny thing is I paid for this service :)
