@Facundo Batista Re: "most probably syncdaemon is not started yet"
Observed on my real (i.e. not vm) PC: gnome-session starts, Empathy, Trackerd are loading and then the hard drive is completely possessed by ubuntuone-syncdaemon, with applet not displaying the Icon (in order to avoid the flickering, as the sources say). Then the applet pops up and says we are disconnected. So syncdaemon is started but not ready to service DBus requests.
