Sorl-thumbnail generates black lines and undesired crops

[Vilial]

I'm using Sorl Thumbnail 12.4a1, Pillow 4.0.0 in a django project

It works fine for most images but for some of them I run into unexpected behaviour.

The original image is portrait jpg 765x1110

After running this code: get_thumbnail('/media/ryzsUIKZVUc.jpg', '464', upscale=False)

I receive a 464x320 image with black background on it's left and right and cropped on top and bottom

this is the original: https://www.dropbox.com/s/ia7906ec19xjhro/ryzsUIKZVUc.jpg?dl=0

and this is the result: https://www.dropbox.com/s/adgut5zkw4xln6e/62b2439654a00312defafddb862eda9b.jpg?dl=0

Tried the latest version with a fix from here:
#233
but still same result

Also tried switching to wand_engine from pil_engine but also same result

I was encountering similar problems, I did some digging and found a couple bugs related to orientation, and was able to temporarily fix it by creating my own engine. See my issue #495 for details on how I fixed it.
