Comment 7 for bug 841332

If you are looking for the generic "Emblems" UI in nautilus, that is a completely separate an unrelated issues to Ubuntu One.

If however, you are not seeing the Ubuntu One emblems on and in your folders synchronized with Ubuntu One, then there is an issue related to Ubuntu One. Having ubuntuone-client-gnome installed allows those emblems to appear.

Which one (or both) of these, are you having a problem with? Emblems appear just fine for me in the Ubuntu One folder, on my synchronized files. If you installed the package, and nautilus hasn't restarted since, then the plug-in would not be loaded, and the emblems would not appear.
