Bug#597588: gnome-power-manager: battery capacity reporting broke on upgrade to squeeze

[Andres Salomon]

Package: gnome-power-manager
Version: 2.30.1-1

I recently updated an XO-1 to squeeze.  The battery icon in gnome no
longer tells me what percentage of battery life is left.  If I click on
the battery icon, it tells me the battery is at 0.0%.  I suspect this
is related to the switch to upower, but I'm not sure what magic dbus
invocations I should be using to tell.

A bit about the machine:

If I run `dbus-monitor --system` while watching for the
'capacity' sysfs entry to change (decrease) doesn't result in anything
UPower-related coming across the system bus.  d-feet does show a
