Short description of error
When trying to move my extruded vertex or edge with G and edge snapping on, Blender immediately closes. I was not able to recreate this in a simplified blend.file so I will just add my project file as it can be recreated there with every vertex and edge there. In addition to this, I had the mirror modifier enabled. Blender is installed through Steam.

Exact steps for others to reproduce the error

  1. Press E to extrude your desired vertex or edge
  2. Enable Snapping-> Egde Snapping
  3. Press G to move your vertex/edge

@Germano Cavalcante (mano-wii) : can reproduce in todays buildbot (rBf1ac64921b49), but for some reason not in Debug builds (rB9516921c05bd)

Does this ring a bell?
