Execute via ssh without X11 forwarding results in seg fault

[tparchambault]

On RHEL86, V1.0.0, the yours-truly user, inadvertently connected to the target system via ssh however yours-truly omitted the -X X11 forwarding option. This resulted in a seg fault and some less than obvious error messaging. I don't consider this a high priority issue, and am not sure whether X11 forwarding can be detected within the ssh session, and whether appropriate messaging should be or even can be generated by the pkexec layer or the fapolicy-analyzer application itself.

The following is the ssh session output along with the journald messages. It is a tremendous amount of noise w/o presenting either a clear or potential root cause or solutions for not having X forwarding enabled. Unless of course, I've just missed it in the wall of words... This is the closest that I can find:

Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused

along with the journald snippet, that got me to look at the gfx connection: error 4 in libgtk-3.so.0.2200.30
