The systray applet is d-bus activated via org.freedesktop.Telepathy.MissionControl5. But the d-bus interface is only started if the applet is present. This creates a circular dependency and the applet is never shown at startup. Reproducible: Always
My thinking is the kded module should start it as that makes some requests on load. One possible problem is that kded module only runs in kde4, so I guess I need to port it?
This works OK now that the whole stack is ported to KF5
