    Check mimetype when bits per pixel not returned by gd (bug #784978)

    Sometimes when creating a thumbnail image, getimagesize doesn't return
    a value for bits per pixel on certain gifs. This creates warnings in
    the logs when approximating the required memory consumption, and also
    refuses to create the thumbnail. We can check the mimetype of the
    image when 'bits' is not set, and when it's a gif, just assume the
    maximum value (8 bpp).
