Package: dbus-user-session
Version: 1.12.20-2
Severity: important
(not sure about the right package)
I first noticed that when I connect by ssh, evince is very slow to
start. A "strace -f -ttt evince" shows a 15-second timeout followed
by a 10-second timeout, thus a 25-second delay, before the window
appears.

A comment at
https://unix.stackexchange.com/questions/676410/evince-is-slow-to-open
based on information from https://bbs.archlinux.org/viewtopic.php?id=224787
(ssh is actually not involved at these URLs) says to run
dbus-update-activation-environment --systemd \
DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORITY
and it initially worked. But when I retried after killing all my
processes, I could see that this does not always solve the issue.
Worse, in my latest try, this command hanged. Perhaps there's
more to do...
According to https://bbs.archlinux.org/viewtopic.php?id=224787
various GNOME applications are affected, so I tried with nautilus
(which I had never used) as it is mentioned there, and I could
also noticed this 25-second delay before the window appears.
