"IIRC abstractions/dbus-accessibility was added to upstream bzr repo after the 2.8.0 release Debian is currently shipping.
Also, I see no reference to this abstraction in the apparmor package, so I suspect this is caused by something you installed manually. Can you please run "rgrep dbus-accessibility /etc/apparmor.d" and send us the result?
