I'm also seeing on upower 0.9.15-3git1 on 12.04. I don't remember this happening earlier from before my mouse showed up as a "power supply" in the applet, so perhaps there is a relation with the mouse.

Bluetooth mouse has already been paired and used with the computer. Mouse does not work when laptop first booted. However, disconnecting/connecting via bluetooth applet (sometimes once, sometimes several times) makes mouse work, but also causes a crash with upowerd. Crash is not predictable. Sometimes it happens on first attempt, sometimes after several.
