The following file is simpler, it works in 2.69 but not in 2.70 and not in 2.71 RC2:

dupli.bug1.blend

It does not work in the UV Map node either (anymore).

The issue was caused by changes to "for_render" flags during the threaded depsgraph commit:
709041ed0b

This replaced widespread usage of G.is_rendering and derived flags by a common EvaluationContext struct with a for_render setting.

Problem is that the previous dupli code was not so strict about the meaning of this flag and now there is some ambiguity: for_render is really only true for full render evaluation ("F12 render"), while false for viewport preview renders. The old G.is_rendering checks were also generating Orco/UV coordinates for previews, but this is now omitted.
