Comment 2 for bug 1098959

I have found a more reliable way to turn the mouse on:
Shutdown a running system with bluetooth turned off.
Reboot, and kill upowerd before enabling bluetooth, then turn on bluetooth and insert mouse batteries -- the mouse will work.
Maybe the package with the problem is not the indicator package, but the upower package, or even the bluez package if it is supplying an API which is faulty.
