Reproduced in 4.3.0b1
Also present in 4.1.5f1 and 4.2.0f2

Light probes only work if there's static geometry in the scene being lightmapped.

2) How can we reproduce it using the example you attached
- Open Scene scene
- Hit play, click on the left and right mouse buttons and see how the lights are being treated as normal lights even though they were marked as baked only, and the character is marked to use probes.

Now to see it working properly:
- Open SceneWithGeometry scene
- Hit play and see how clicking on the left and right button have no effect now

Note that this isn't a problem of just editor, it is also a problem of standalone builds and at least iOS builds too.
