hey glad you have a workaround, but diffuse depth = 0 means no GI at all, seems like a shame to disable it.
I'm pretty sure you could get it working with gi enabled, but its hard to tell without seeing a scene where the problem is. if you attach a scene please make sure you remove all textures and make it as simple as possible while still reproducing the issue.
