Broken: Current Buildbot builds, own builds
Worked: Official 2.78c

Short description of error
Importing simple OBJ files (e.g. coming from Maya) fails. This error message appears:

Traceback (most recent call last):
  File "H:\blender-git\build\bin\Release\2.78\scripts\addons\io_scene_obj\__init__.py", line 148, in execute
    return import_obj.load(context, **keywords)
  File "H:\blender-git\build\bin\Release\2.78\scripts\addons\io_scene_obj\import_obj.py", line 1258, in load
    unique_material_images, use_image_search, use_cycles, float_func)
  File "H:\blender-git\build\bin\Release\2.78\scripts\addons\io_scene_obj\import_obj.py", line 363, in create_materials
    context_mat_wrap = cycles_material_wrap_map[context_material]
KeyError: None

location: <unknown location>:-1

The same OBJ files open fine in official 2.78c
The OBJ also opens fine in latest builds if I delete the corresponding MTL file

Exact steps for others to reproduce the error

Switch to Cycles
Try to load attached OBJ file with a current build
Fail

Hand.obj

Hand.mtl
