John,

There should be errors in this file connected to atril and core dump.

As systemd is now in control of ubuntu systems (systemd replaced
upstart), you might try journalctl as a way to get to the systemd log files.

journalctl is VERY complicated, however. See

https://www.digitalocean.com/community/tutorials/how-to-use-journalctl-to-view-and-manipulate-systemd-logs

https://www.freedesktop.org/software/systemd/man/journalctl.html


For now, try this terminal command:

$ journalctl /usr/bin/atril

to give you all entries that involve atril.

You probably want to type the END key to see the last set of entries.

Here is what my laptop displayed at the end:

Note as well that atril runs without a visible hitch for me. So, many
errors are just normal background noise. What you need are the errors
connected to the core dump.
