Faces misaligned?

Hi all,

Great package - much faster than many of the other options.

I'm running into an issue where, for some images, the boxes are drawn in the incorrect place. The number of boxes is correct, it just looks as though the boxes have been shifted left. See an example below.

(The image is just a random photo from the internet. The original image is here)

I've been over the code and I cannot see why this would occur. I've also tried resizing the image, including changing the aspect ratio, and the result is the same. Has anyone had a similar experience?

Edit: To be clearer - it only occurs on some images, not all. So I don't think it's a problem with the install.
