Bug#1089760: autostart apps are delayed with gtk4 from experimental (4.17.1)

Package: libgtk-4-1
Version: 4.17.1+ds-2
Severity: normal

Hi,

autostart'ed apps are appearing delayed on my desktop after switching
gtk4 from unstable to experimental. I tested with the following
in "Startup Application" from gnome-tweaks:
- firefox
- gnome-terminal
- gnote
- gnome-text-editor

If running with gtk4 from experimental (4.17.1), firefox appears
immediately after login, gnote and gnome-text-editor appear
after a 30 second delay and gnome-terminal doesn't appear at all.
If running with gtk4 from unstable (4.16.7) all appear immediately
after log as expected.
I ruled out any interference from some gnome-shell extension by
disabling all extensions.
The only clue in the logs is

org.gnome.Terminal.desktop[16035]: # Error constructing proxy for
org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling
StartServiceByName for org.gnome.Terminal: Timeout was reached
