Bug#898698: gdm3: GDM logon fails for some users: "Could not finalize jump to vt1"

Package: gdm3
Version: 3.28.1-1
Severity: important

Some users after logging on are returned to the login screen after a few seconds. In /var/log/syslog I find:

GdmSessionWorker: couldn't finalize jump to VT 1: Unterbrechung während des Betriebssystemaufrufs

(that's "Interruption during the operating system call")

I have already deleted everything related to session and session state for
those users, but this doesn't seem to make a difference. So I am pretty lost
where to search further. This is observed both with the Wayland and the X
session of GNOME
