No user list window shown

Link to original bug (#681826)
Description
Running
$ gnome-screensaver &
$ gnome-screensaver-command --activate
and then clicking on »Switch user« for the first time on this system the user list was not shown in the new X session(?) (on tty8). The background was loaded correctly and I could move the mouse. But no window was shown at all.
Killing gnome-session-worker, GDM in that window started correctly.
This is Debian Sid/unstable with gdm3 3.4.1-2.
I attached to all GDM processes with GDB and run t a a bt full
. I am going to post the backtraces as comments. But I do not even know which process is responsible to draw that window.
Version: 3.4.x
