It solves partially ;)
No more gnome_init error...

I've tried the example, and I've found a bug in the libpanel-2.0 vapi.

I don't know if this is the correct (definitive) solution, but for now
you have to change this line in the libpanelapplet-2.0.vapi file
(usually is installed in /usr/share/vala/vapi/)

from
        public static int factory_main (string iid, GLib.Type applet_type,
AppletFactoryCallback callback);

to

        public static int factory_main (string iid, GLib.Type applet_type,
AppletFactoryCallback callback, pointer data);


And then changed your code from

var ret = Panel.Applet.factory_main ("OAFIID:Vala_Applet_Factory",
typeof(Panel.Applet), (Panel.AppletFactoryCallback)
MainApplet.panelFactory);

to

var ret = Panel.Applet.factory_main ("OAFIID:Vala_Applet_Factory",
typeof(Panel.Applet), (Panel.AppletFactoryCallback)
MainApplet.panelFactory, null);

and it should works.

Ciao,
Andrea
