System Information
Win 7/64, AMD HD 6850

Blender Version
2.69 r60995, 2.70 2d4de27

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.

Confirmed, this worked in 2.69 too.

Before mistakenly opening another task, I'd better ask if I misunderstood something: The result did not change in the newest release. This means, referring to the blend I posted, on the right side, there is still the sphere in the middle rendered but not the cube even though both are children of the object of which DupliFaces is activated. Thanks in advance for clarification. (In any case, thanks for all your quick fixes BTW!)
