Relevant dbus-monitor output:

method call time=1702674565.591500 sender=:1.64 -> destination=org.freedesktop.DBus serial=728 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=StartServiceByName
   string "org.mate.panel.applet.DockAppletFactory"
   uint32 0

lots and lots of spam...

   string "Could not get owner of name 'org.mate.panel.applet.DockAppletFactory': no such name"

I tried to debug this as much as I could, but that's as far as I could get. I do have a /usr/share/dbus-1/services/org.mate.panel.applet.DockAppletFactory.service file that contains the following:

[D-BUS Service]
Name=org.mate.panel.applet.DockAppletFactory
Exec=/usr/bin/env python3  /usr/lib64/mate-applets/mate-dock-applet/dock_applet.py

so I really have no idea why it can't start it.
