I don't think it is Evince-specific either, but that was the only app
that I encountered having the issue. It's definitely not X related
however since this is Wayland-specific. The "wayland-0" socket naming
convention seems to come from libwayland-server, so maybe that's a
reasonable package to provide a Wayland abstraction, but then that needs
to be included in the Apparmour profiles for GUI programs.

Note also that the socket name may change depending on the server
implementation or at runtime via the WAYLAND_DISPLAY environment
variable (which works much in the same way as DISPLAY does for X), if
that does happen then the same problem will occur. I don't know how to
fix that in Apparmour though.

Title:
  Evince's Apparmour profile prevents opening docs from other apps under
  Wayland

Status in AppArmor:
  New
Status in apparmor package in Ubuntu:
  New

Bug description:
  Evince fails to run when launched from another app (Nautilus, Ephy,
  etc) and running under Wayland. For example, nothing appears to happen
  when double-clicking on a PDF file in Nautilus. Evince is launched,
  but its Apparmour profile is preventing access to a Wayland socket,
  hence it immediately exits.

  The following is typical of the reported error:

  > Oct 19 15:06:40 payens kernel: audit: type=1400
  audit(1445227600.333:26): apparmor="DENIED" operation="connect"
  profile="/usr/bin/evince" name="/run/user/1000/wayland-0" pid=12956
  comm="evince" requested_mask="wr" denied_mask="wr" fsuid=1000
  ouid=1000

  Adding the following lines to it's local Apparmour config and
  reloading Apparmour fixes the problem:

  >  owner /run/user/*/wayland-* rw,
  >  owner /run/user/*/weston-shared-* rw,
