[Bug 1507469] [NEW] Evince's Apparmour profile prevents opening docs from other apps under Wayland

 

You have been subscribed to a public bug:

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,
