Cycling mouse and/or bluetooth never crashes the upowerd for me.  I do get some null pointer stack dump from the bluetoothd at some point.  Closest complaint was :
quanta4g kernel: [  211.852064] power_supply hid-00:60:D1:00:C3:15-battery: driver failed to report `capacity' property: 4294967291

Here's the null pointer log:
