Hi,

I can replicate this as it happens almost every time (3 out of last for 
attempts) I close the Xorg server. It happens on FreeBSD 10.1-STABLE #0 
r275689 with generic kernel. What I don't understand why the instruction 
pointer is 0x0 and where to go from here. I'm running latest packages 
from the ports tree.

Someone please let me know there is a path to go from here:

Thanks,
