Yes, it was the script in the end! See Maksim Orlovich's comment when he 
pointed out that a fill() call was needed to initialize the QImage, after 
creating it. When I added that, both Ruby and C++ versions of the code worked 
fine.

    pic = Qt::Image.new(256, 256, Qt::Image::Format_ARGB32_Premultiplied)
    pic.fill(0)
