btw if you run your script just before lauching sugar, it is not being
ignored, sugar just never get it.

No idea how you managed to make it run. the cron process shouldn't know
dbus session ($DBUS_SESSION_BUS_ADDRESS) and sugar never get the signal
sent from cron process.

If you just, for some reason, need to send dbus signal to sugar on its
startup, use dbus-send command, eg, from .xsession file:

    send() {
        # wait for sugar start
        sleep 3
        dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.Notify string:"app" uint32:0 string:"icon" string:"summary" string:"body" array:string: dict:string:string: int32:0
    }

    send &

    exec sugar....
