Short description of error
I set an object as a child to another mesh, and set the parent to use duplifaces. And although the duplicated objects appear just fine in the viewport, if I set the viewport to Rendered mode, or do a final render, the duplicated objects do not appear at all during the render. I've already confirmed that the obvious culprits (visibility, scene layers) are not to blame.

Rendering tested with cycles in CPU and GPU mode, and I tested with blender-softwaregl as well, same results. Problem also occurs when using Blender Internal. I also tested releases 2.73a and 2.72b, same issue.

Strangely, I've used duplifaces with other things, and had no trouble.

Exact steps for others to reproduce the error

1. Open the following .blend file:
   ChildObjects_WontRender.blend113 KBDownload
2. Set the viewport to Rendered mode. The objects do not appear except outside the render boundaries.
3. Run a final render. The objects still do not appear.
