Added an apparmor task as this should probably be fixed in
/etc/apparmor.d/abstractions/gnome which is installed by apparmor.

I looked at this only because of https://community.ubuntu.com/t
/failed-to-preview-print/7956 where a user "flaviosm" reported the
same thing.
In `dmesg` I noted the following
[43361.474096] audit: type=1400 audit(1536710182.492:65):
apparmor=“DENIED” operation=“exec” profile="/usr/bin/evince"
name="/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop" pid=11840
comm=“evince” requested_mask=“x” denied_mask=“x” fsuid=1000 ouid=0
I rebooted and tried again, (same result)
[ 400.208807] audit: type=1400 audit(1536711261.421:51):
apparmor=“DENIED” operation=“exec” profile="/usr/bin/evince"
name="/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop" pid=5302
comm=“evince” requested_mask=“x” denied_mask=“x” fsuid=1000 ouid=0
Note: I don't have a printer setup on my box (I don't print from
it), so this could be the cause! I don't know if this applies to
"flaviosm" too.. I can connect & test after printer is setup if
deemed helpful (headcold - so no motivation currently)
Filed online as unsuccessful via via `ubuntu-bug` on actual box..
