Looks like you're using 2.79a0?  Can you try with an official 2.79b/c build?

It has no problems with the official 2.79. But the official is missing far to much functionality, I don't think most people use it.

Unfortunately supporting unofficial builds of blender is a bit of a rabbit hole for us.  As you can imagine.  However I can give some insight here.  Not sure if you build that version yourself or what, but make sure you have python libs "ffi" installed when building blender.  It appears that library is missing from the python inside blender.

Barring that what version of python is in your blender build?
