Short describtion: Edge snapping a curve's vertex causes blender to crash

Exact steps for others to reproduce the error
a) Create a plane
b) Create a bezier curve and go in it's edit mode.
c) Turn on snapping , to EDGE. (vertex seems to be ok)
d) Select a vertex and try to snap it to an edge of the plane. At that moment blender crashes.

p.s: funny thing if you snap first to a vertex and then to an edge, there is no problem.
