Unclear error message when processing certain images

[RobinDeBock]

I'm not allowed to disclose the images that cause the error, however the error message isn't really clear.
The first step in determining the source of the mistake is to provide a more informative error message.
As 5% of my 500-image test batch could not be processed, this isn't something to overlook.

The error message is:
{'self': <smartcrop.SmartCrop object at 0x7fc57b26cb50>, 'image': <PIL.Image.Image image mode=RGB size=299x269 at 0x7FC57B2CA4D0>, 'crop_width': 300, 'crop_height': 200, 'max_scale': 1, 'min_scale': 1, 'scale_step': 0.1, 'step': 8, 'image_width': 299, 'image_height': 269, 'crops': [], 'scale': 1.0, 'y': 72, 'x': 0}

I suppose this is from https://github.com/smartcrop/smartcrop.py/blob/master/smartcrop.py#L215, which happens when the algorithm can't find any viable crop. I'm not the original creator so idk why precisely that happens, but in this case I'd suggest doing a naive crop where SmartCrop fails.
