Blender Version

Short description of error
Blender crashes after deleting vertices.

Exact steps for others to reproduce the error
The crashing blend file
crash.blend
Cut the left part (cut through on) and delete vertices on the right side of the cut (images 1,2). Cut the right part and when trying to delete the vertices on the left of the cut blender crashes. For some reason the exact order of the steps is important else blender doesn't crash.
