The problem is that you are creating an out of process applet, using PANEL_APPLET_OUT_PROCESS_FACTORY, but defining it as in process in the panel-applet file, InProcess=true. You can just remove both keys InProcess and Location from the panel-applet file and use a dbus service file to activate the applet. > Thanks.
