There's a long standing bug in the input stack somewhere that has been
hard to nail down. We haven't been able to reproduce it ourselves, and
it seems to affect a small minority of people, so it's lingered. Our new
stack that will be in Precise will have a completely different
foundation, so this bug will disappear anyway.
The issue seems to be some bad state in xserver-xorg-input-evdev.
Removing the kernel driver and reloading it fixes things:
$ sudo rmmod hid-magicmouse
$ sudo modprobe hid-magicmouse
I'm sorry I don't have any better info right now...
