Messages about removing obsolete conffiles are normal, as dbus config files have moved form /etc to /usr; and upstart jobs are no longer needed as upstart is not required anymore.
I am suspecting if one reboots after an upgrade eveyrhting is fine.
I believe we also need to potentially reload dbus configuration, after the dbus files are moved to /usr and I'm not sure if this is done already or not.
I will investigate further the upgrade issue you are pointing out.
