[Campbell Barton]

Hi Ken, if you know about python memory reference allocation, theres a 
serious bug in Mathutils.Vector comparisions.
doing an ...
if vec == None:
....
Will segfault Blender because None needs an extra reference.
- I have a fix hinted in thge bug report but not sure if its only doing 
the reverse and unnecceraly increasing the references for objects that 
dont need it.
