`block in calc_faces': undefined method `*' for nil:NilClass (NoMethodError)

I assume it's an issue with that image file but I don't know where to start debugging.

Happened again. Looks like an issue with rotated photos.

It seems there is a problem with the image rotation factor, it is neither 0 nor 90, 180 or 270 degrees. I don't quite believe that to be the case though ... I have uploaded another patch that can serve as a fallback, In this case the faces might be positioned incorrectly but the app shouldn't stop at the image. Can you try the updated version?

Thanks for the patch!
