Worked: (optional)

The Image node in Compositing can't read Z buffer of openEXR in 2.79, You can use the following two methods to verify:

1, open my upload file, just press F12, than F3 save the image to OpenEXR with check ZBuffer option, than open the image in blender 2.78 and 2.79, you can see in 2.79rc1, the image node dont have the z channel output dot

2, or load the .exr file from my upload, you can see the image node in 2.79rc1 dont have z output node;

Sorry for my poor English:D

Seems like rB556942ec0782c5641c removed Z pass for non-render image nodes, not sure why…

@Lukas Stockner (lukasstockner97) that one is for you I bet.

This is a regression and must be addressed before 2.79 final release.
