--- Operating System, Graphics card ---
Win7 64bit; Nvidia GForce 560

--- Blender version with error, and version that worked ---
Crash: Blender 2.68 RC1
Does not work (but no crash): Blender 2.67

--- Short description of error ---
Blender crashes when I add a mesh without faces (only verts and edges) and I add a skin modifier, then a remesh modifier and I check the "show in edit mode" button and enter the edit mode. With the Blender 2.67 it didn't show the result but didn't crash as well. Meshes with one face or more work well.

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Open attached Remesh_Edit.blend and press Tab to enter edit mode - 2.68 RC1 crashes.
