Addendum: This bug was present on 16.04 too, but running "dropbox stop && DBUS_SESSION_BUS_ADDRESS="" dropbox start" after login fixed the Dropbox icon. It no longer works in 16.10; the command runs successfully
dropbox stop && DBUS_SESSION_BUS_ADDRESS="" dropbox start Dropbox daemon stopped. Starting Dropbox...Done!
but the icon remains as a rectangle with a red lined circle inside it (same as in wgarcia's video) that shows no info.
