devicekit-power shows wrong maximum charge

Binary package hint: devicekit-power

I have a two-battery system. The smaller battery, which discharges first, has a rated capacity of 23.74 Wh according to `devkit-power -d`. However, the same `devkit-power -d' shows:

energy-full: 43.82 Wh

which is incorrect. This causes the battery to be reported as only half-charged, even when it is fully charged.

The `acpi` utility correctly reports the charge:

Battery 0: Discharging, 73%, 01:42:34 remaining
Battery 1: Unknown, 99%

This is on a fully-updated version of Karmic, with version 011-1ubuntu1 of devicekit-power.
