Looks like recent changes in the Wacom driver made the Bamboo ONE crashes. The tablet behaves as if it was a regular Bamboo device with pen, touch and pad, but there is no physical pad connected to it.
The weird part is that the pad is still sending events and given that there is no input node connected to it, we get anull pointer exception.
