[Bug 1877532] [NEW] at-spi-bus-launcher does not terminate at end of X session

[Daniel Richard G.]

Public bug reported:

This concerns at-spi2-core 2.36.0-2 in Ubuntu focal.

I log into the Xfce desktop as "skunk" via xrdp, and then logout.

A few minutes later, "loginctl list-sessions" shows the following:

    SESSION UID USER SEAT TTY
          9 0 root
        c10 1000 skunk              
         c9  116 lightdm seat0   

    3 sessions listed.

Output from "loginctl session-status c10":

    c10 - skunk (1000)
    	   Since: Fri 2020-05-08 04:03:51 EDT; 6min ago
    	  Leader: 6009
    	 Display: :11
    	 Service: xrdp-sesman; type x11; class user
    	   State: closing
    	    Unit: session-c10.scope
    		  ├─6184 /usr/libexec/at-spi-bus-launcher --launch-immediately
    		  └─6199 /usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 3

These two processes stick around forever until I kill them, or their
parent "systemd --user" process. Only then does the session disappear
from list-sessions.

When I run "session-status" while I'm logged in, I see a list of about
20 desktop-related processes. All of them except these two go away on
logout. These should too.

(Note that this problem does not occur when I log in/out via LightDM on
the console.)
