Lost control of keyboard

[Dry Hairy Tree]

Hi

I can't give you a bug report I had to manually shut off the computer as I lost all control of the keyboard and mouse while playing the latest experimental version about 5 minutes prior to this post. I wasn't doing anything just running along then all of a sudden stopped in the midst of an ore patch and all controls were gone.

From my typing here, I can safely assume it wasn't the keyboard.
