When I try to Import a OBJ file on the newest version of Blender it wont work.

When It loads in nothing loads in at all. Just blank I checked way to fix this cant find anything, I went into user preferences to ad-ons I have wave front added. Pleas someone help me!

Manuel posted this obj file reproducing the error
EDIT - specifying "you should also say that the error happens only with Cycles as selected engine and only if the obj has more than one material."

I have reproduced the attribute error below even with a simple object with two polygons and two materials:
-------------------
scripts\addons\io_scene_obj\import_obj.py", line 318, in create_materials
context_mat_wrap.hardness_value_set = 1.0
AttributeError: 'CyclesShaderWrapper' object attribute 'hardness_value_set' is read-only
-------------------
Here is the plain txt of test obj and related mtl:

hi, confirming there's an issue here, possibly related to the recent materials change

@BrendonMurphy Confirmed priority is more than enough here, unbreaknow is for absolute critical bugs (those that might generate data corruption, break your machine…).
