The problem is a change in the file
/etc/X11/Xsession.d/20x11-common_process-args
Replacing line 36:
STARTUP_FULL_PATH=$(command -v "${1%% *}" || true)
with this:
STARTUP_FULL_PATH=$(/usr/bin/which "${1%% *}" || true)
removes the error.
The question is now: WHY was there a change from "which" to "command
-v"?

Title:
Recent commit breaks /etc/X11/Xsession
Status in xorg package in Ubuntu:
Confirmed
Status in xorg package in Debian:
New
Bug description:
The following command:
$/etc/X11/Xsession true
opens a dialog with the following error message:
"Xsession: unable to launch "true" X session --- "true" not found;
falling back to default session."
There is a "Okay" button on this message, and clicking it does bad
things if one happens to be running Ubuntu 22.04 on Xorg (or running
Gnome on Xorg, which is seemingly a different option for the the low
latency installation I am running: 5.15.0-43-generic #46-Ubuntu SMP
Tue Jul 12 10:30:17 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux).
See Brendan O'Dea's related comment about this behavior on debian-
bugs-dist: https://www.mail-archive.com/debian-bugs-
d...@lists.debian.org/msg1857023.html
This has consequences in my use of xpra. For example, if I use xpra
via the run_scaled-master script to magnify a single application's
interface for a 4K display I get the error dialog mentioned above,
often with resulting system instability.
This behavior cropped up last month.
