The compositor crashes when attempting to read an EXR layer called Alpha from a multi-layer EXR file. This is because Blender exposes an extra output in the Image node called Alpha, which is not a real pass, but is derived from the combined pass. So, this special case conflicts with an actual pass called Alpha. To fix this, we only consider the special case if the pass name is the combined pass.
