System Information
Windows 7 64Bits GTX980Ti + GTX580 + i7 2600K

Blender Version
Broken: 2.78 ec6b593
Also present in latest from builbot 2.78 9ea71bc

Short description of error
Rendering attached file with Cycles crashes, both on CPU or GPU.
Even entering Rendered View in the viewport immediately crashed Blender

File contains only a simple bezier curve object created from a regular default bezier curve.

Exact steps for others to reproduce the error

Just try rendering Crash.blend with Cycles or entering rendered view in the 3D viewport.
Even after conversion to mesh object still crashes on render, both CPU or GPU

My computer normally renders everything just fine, had not experienced a Blender crash in quite a while, so hope this is easily reproducible.

EDIT It seems to be related to material slots. Adding a new material slot to the curve will no longer cause a crash on rendering.

Ok, I seem to have made some headway in pinpointing the source of the crash, it seems to be something related to material slots.
Reported curve in attached file has no materials nor material slots assigned, but simply creating a new material slot, even if no material is added, will no longer cause a crash upon rendering.
