This needs to be reported upstream against XFCE.
They might ask for a backtrace.
https://docs.xfce.org/contribute/bugs/start#backtraces
Debian specific instructions:
https://wiki.debian.org/HowToGetABacktrace
For simplify, you’d need this package too:
debug-misc opt-in package to easily enable debugging
Let me know if anyone wants to proceed debugging this.
@Patrick:
The segfault, right, should be reported, sure, when I get my Whonix system hardened I might do this (will let you know by that time). But the original aim of reporting the console messages was to tackle the slow shutdown. So was the “stop job” with the timer the culprit here?
Possibly.
Taking a long time on the screenshot. And just before that, the segfault.
I might be able to say more when systemd journal logs are provided as per Slow shutdown of version 15 workstation and gateway
@Patrick
I got the journals, but I cannot post them here: “Body is limited to 50000 characters; you entered 453602.”
@rk1 Thank you for also speaking up about this issue and picking up where I left off 
re giving the journal logs.
@Patrick
The files were too big for paste.debian also. So you can download them here:
with password: 6WkznRLkYhs3bXQ
Please don’t share otd (libre office or so) files. Plain text much better. However the workstation log was plain text and it gave another lead.
Last OK message:
Jan 24 11:12:08 host systemd[1]: Stopped Encrypted Swap File Creator.
Then takes a long time. Then:
Jan 24 11:13:38 host systemd[1]: session-1.scope: Stopping timed out. Killing.
Jan 24 11:13:38 host systemd[1]: session-1.scope: Killing process 1956 (lightdm) with signal SIGKILL.
Jan 24 11:13:38 host systemd[1]: session-1.scope: Failed with result ‘timeout’.
Jan 24 11:13:38 host systemd[1]: Stopped Session 1 of user user.
Would require debugging lightdm.

Added some instruction on how to get a lightdm debug log just now:

That log looks very similar to mine and I don’t see any errors there. Looks like proper termination.
I have no idea.
I suggest to report a bug against Debian.
And/or upstream original developers.
They might ask for a backtrace.
(similar this post Slow shutdown of version 15 workstation and gateway)
@Patrick
I want to report the bug like you suggested, but how to do so is not crystal clear. First problem I have is you say it is a lightdm bug. How do you know it is? Second when I go to launchpad -> robert-ancell, I see lightdm is one of his packages. But everywhere it says lightdm in Ubuntu. And the problem of slow shutdown arises in Whonix. Or you mean to say that lightdm as used in Whonix is the same lightdm used in Ubuntu?
Because the log contains:
This means systemd sends the usual sigterm signal which lightdm ignores and then when that didn’t work it sends the sigkill command. I.e. lightdm does not react to sigterm for some reason.
No. Lightdm from Debian https://packages.debian.org/buster/lightdm
You could report to Debian too and the Debian maintainer should in theory forward the bug upstream. But my experience is this takes a long time. It is useful to report bugs to Debian. Often the maintainer or someone knows something. But contacting the upstream developer directly makes sense too.
Don’t assume it’s more clear to me. 
Just contact upstream somehow. Then see how it goes. Preferably in public to have a reference and give others to share their thoughts well. I’d open a bug on launchpad even if’s not 100% correct that’s not a crime. If it is the wrong place, someone will point out a better place.
Ok, filed a bug-report on launchpad with Robert Ancell.
Link?

I am currently avoiding the problem by just forcing shutdown for WS/GW. It is ugly but I only use read-only version so dataloss is not an issue.
Me too bro.
Hey guys, heads up, I have found the solution.
Just up your ram to 2gigs. It has solved the issue for me.
I wanted to increase specs on the workstation for other reasons and noticed this problem was not occuring any more and so upped it to 2gb on the gateway as well and it seems to have fixed it there too.
EDIT: Just switching to 2 gig didn’t seem to do it, but increasing cpu too seems to have worked, if not that then keep upping them til it does as the workstation works consistently and I have that at 4 cpu/4 gig I think.
Though it depends how much you wanna use just to solve that issue :). My local machine rarely is needed for much so I can afford to use it for the short instances I want to run whonix.
If you are increasing cpu count while pinned then you won;t be really getting any increased perf benefit.
