[feisty] A "plug" icon is displayed instead of battery and I get no charging/discharging information, while hal gives it correctly

Binary package hint: gnome-power-manager

I have an icon representing a plug in gnome-power-manager, and if I hang my pointer over g-p-m I don't see any percentage. If I kill g-p-m and restart it, it goes fine and shows the battery. If I unplug the power cord, the screen is correctly dimmed but the icon is not updated, and everything is ok in /proc/acpi and hal:

vincenzo@frattaglia:~$ cat /proc/acpi/battery/BAT1/state
present: yes
capacity state: ok
charging state: charging
present rate: 17539 mW
remaining capacity: 42552 mWh
present voltage: 11260 mV
