Public bug reported:
The default apparmor 'X' abstraction permits access to
/{,var/}run/lightdm/authority/[0-9]*, ostensibly for the xauthority
file. Except on Trusty, that's not where the xauthority file is. It is
instead in /run/lightdm/$USER, and named "xauthority". I have had to
udpated my apparmor configuration, lest apparmor convince Evince of
being a filthy script kiddie, out to corrupt my xauth file.
Please consider adding the following to the 'X' abstraction:
owner /{,var/}run/lightdm/*/xauthority r,
