My laptop's battery is bigger than yours

Somehow, since a few weeks ago, occasionally gnome power manager loses its 
mind and starts telling me that my laptop battery's "last full charge" is 
946.0 watt-hours of juice. Which makes the battery percentage indicator 
pretty much meaningless.

I can usually set things back to normal by charging up the battery to its 
true max capacity, 63 watt-hours, and rebooting. After the reboot, 
gnome-power-manager gains back its sanity, and usually continues to behave 
itself, for several cycle charges and reboots. But, invariably, after a few 
days gnome-power-manager once again becomes convinced that my laptop's got a 
nuclear-powered battery.

It's beginning to get rather old, and annoying. It looks to me like somehow, 
somewhere, gnome-power-manager saved an erroneous power reading, once upon a 
time, and keeps going back to it. I tried looking in gconf, trying to 
figured out where gnome-power-manager saves the last full charge reading, 
but had no luck. Anyone knows?
