Short description of error
This crash happens in a really special case if two or more faces and one edge are connected in one vertex (as in attached .blend). Trying to rip the edge from the connecting vertex instantly crashes Blender.

Exact steps for others to reproduce the error
Open attached .blend file, select the vertex which connects the faces, press V to rip the selected vertex while hovering the mouse over the single edge connected to the the faces. Ripping the faces from the center vertex works fine.
