blender render doesn't finish #6
Description
I've been trying to get the rendering through blender to work. After some tinkering with blender version (->2.79!) and the matching older version of the LDraw Addon I was able to manually render parts from ldraw inside the blender UI. I couldn't get the render.py script to work though. It seems to start rendering. The render doesn't finish though. So far I've waited about an hour for a single image. There is no CPU and GPU usage by blender or the script, so I suspect it is blocked somehow. This is the output:

After a few hours I hit ctrl-c:
^C
Sent an internal break event. Press ^C again to kill Blender
But that didn't end either. Had to ctrl-c again to kill the process, which worked.
Any ideas what I might have missed?
