desktopcouch-service crashed with RuntimeError in find_port__linux()

[Pedro Gomes Rocha]

Binary package hint: desktopcouch

I just upgraded Ubuntu and installed Ubuntu One and the integration with Firefox, to sync bookmarks. When i restarted Firefox to use the extension, after set the password, the crash message apears.
I rebooted the machine to ensure that the system was upgraded correctly, and is everything fine, except this Ubuntu One & Firefox bookmark syncing.
