I have the same problem too but i have found that if you kill the gnome-
power-manager process and start it again you get the icon!!
Before this update i am sure the battery icon was taken from the icon
theme that you are using now when i restart the process to get the icon
it uses a generic one
I decided to start the process in a terminal for debuging puposes and
this is what i get. Hope this helps :)
