Ubuntu 18.10 Evince of a PDF

Clicking PREVIEW I get busy awhile then

Failed to print document
Failed to execute child process "/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop" (Permissions denied)

I looked at this only because of https://community.ubuntu.com/t/failed-to-preview-print/7956 where as 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,

[ 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 motiviation currently)

Filed online as unsuccessful via via `ubuntu-bug` on actual box..
