Comment 2 for bug 414879

I have this same problem. The applet is present for a minute or so when I logon to my computer, or if I disconnect and then reconnect from inside the Ubuntu One folder in Nautilus, but disappears soon after. It is still running, as a ps shows as well as the "Ubuntu One client applet already running, quitting" error message in the terminal. Also, dragging and dropping files into the nautilus folder correctly syncs the file with the service.
