Public bug reported:
Sometimes after I unplug the power cable I get this:
$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: charged
present rate: 22191 mW
remaining capacity: 34980 mWh
present voltage: 11498 mV
The "charging state" line is cleary wrong and mistakes HAL into this:

saying it's not charging or discharging.
This is a white macbook 2.0Ghz core duo laptop.
