Gnome Power Manager is failing to update both level of charge and un/plugged status

I can confirm this behavior. I am using Feisty and this bug was introduced with the last update! Today is the 11th of June.

I first was not sure if this is a kernel acpi issue or the fault of gnome-power-manager. From what I saw so far, the truth must be in some layer in between!

ACPI seems to be working and seems to recognize when a battery is plugged in:
elias@doroga:~$ sudo acpi -V
     Thermal 1: ok, 53.0 degrees C
  AC Adapter 1: on-line
elias@doroga:~$ sudo acpi -V
     Battery 1: charging, 100%
     Thermal 1: ok, 55.0 degrees C
  AC Adapter 1: on-line

But both, gnome-power-manger and battstat-applet-2 are not seeing this happening as it seems. They stay with what was detected at startup as described above.

Note again, this was introduced with the latest update! It was working last week!

Fwiw, I think this relies on hal for doing the updates. Perhaps hal is not running on your system or something?

Actually, this seems to be a kernel issue! I downgraded from 2.6.20-16.29 back to 2.6.20-16.28 and everything is alright again!!!

The bug does not derive from gnome-power-manager itself! When I downgrade from linux-image-386 2.6.20-16.29 back to 2.6.20-16.28 everything is alright again!!!
