Several blender-heads reported to me that the add-on isn't working with Blender 2.78. I'm currently looking into it. I'm trying to narrow it down and making some progress, but it is a though one. I don't get any python errors. Just the error: Segmentation fault (core dumped). I'm going to figure it out, but it will take some time. Please be patient. If you have any suggestions where to fix this, please let me know!
After some digging I thought is was a bug in Blender itself. I reported it as such and I just got confirmation about it. You can follow the progress here: https://developer.blender.org/T49828
Thank you all in advance.
Have fun with Blender!
