Battery Monitor not working (neither the battery applet) on Hardy

Binary package hint: gnome-power-manager

After today updates(08/02/21) the battery monitor isn't working(not showing) al boot time. If i connect the charger -> it shows, but it doesn't update the battery status. Also, if i disconnect the charger, and connect it again it works. (but not auto-updates).
