No face is found in the given image - 1.2.0-mobilenet-gpu

I installed 1.2.0-mobilenet-gpu and I keep on getting "No face is found in the given image" on a bunch of pics clearly have nothing but the face only. The same group of pics work fine on the cpu version of 1.2.0.

Start by reproducing the failure with the same images on 1.2.0-mobilenet-gpu and the CPU version, as described in the issue. Trace the face-detection path for the GPU model and compare its result with the CPU path; done means the GPU version detects the same faces or the incompatibility is clearly documented.
