Short description of error
In this particular scene, setting the bevel modifier width at 0 make blender crash.
This was the case with other objects in the scene. I've deleted them to simplify the scene.
I've tried to reproduce the crash with the default scene (cube) and it worked without errors.
Exact steps for others to reproduce the error
Open the attached file, set the bevel width to 0 and that should crash blender.
