Bug Description

I was trying to pair a snowball running the 12.05 rc image with my phone, and it froze up after clicking the button to confirm at the pin matched what I saw on my phone.

At this point, I could not move the mouse, nor could I get any response from the serial console. I was previously able to pair a headset successfully though.
