**Short description of error**
If a group instance is rendered and the group contains a mesh with DupliFaces activated, and one of the children is an instance of another group, the render result of the superordinated group instance contains not only duplicates of the subordinated group instance but also the original of that instance. - but it's not as complicated if you look at the steps described below. :)
**Exact steps for others to reproduce the error**
Open the attached file and look at the viewport:
- On the left, there's a sphere belonging to Group.001
- In the middle, there's a mesh with 4 faces. DupliFaces is activated. The mesh has two child objects: a cube and an instance of Group.001. If you render, neither the child objects themselves nor the 4 faces are rendered. Only the duplicates are rendered. That's ok and the expected behavior.
- The mesh and it's two children belong to Group.002. On the right, there's an instance of Group.002. In it's render result, the sphere is shown in the center but not the cube. This is an inconsistency how group members are handled: If a group member is an object, it's not rendered but if it's a group instance, it is rendered. This should be handled consistently.
