Hi, It seems the bug, at least in my case, was caused by the acpi battery kernel module reporting the battery as connected and disconnected continuously.
Since I upgraded my kernel to 3.2.18-1 the battery icon stopped flipping on and off and the cpu use by upowerd is pretty much normal. upowerd --monitor shows a change in battery state every 20 seconds or so: upower --monitor Monitoring activity from the power daemon.
