Backtrace stopped: previous frame inner to this frame (corrupt stack?)

I was building some packages in the background at the time. I was ssh'ed in
from a linux box, and running x2x to allow me to move the mouse and keyboard
from the linux box to the DF box. At the time of the lock up, I was moving
the mouse around on the DF box. Though I have no idea if that's related to
the crash, that's the only thing that comes to mind.
