Smartcrop with width or height littler than 32 not working

[rafaelsq]

$ docker run --rm -p 9000:9000 h2non/imaginary -enable-url-source
$ curl http://localhost:9000/smartcrop?width=31&height=31&type=webp&url=https://camo.githubusercontent.com/bcb3b2bd343c3c85aaf6094e51c6178bbe239a32/687474703a2f2f7331342e706f7374696d672e6f72672f3874683731613230312f696d6167696e6172795f776f726c642e6a7067
{"message":"Error while processing the image: shrink: parameter vshrink not set","code":1}

but if you increment the with to 51 or the height to 32, it will work.

any ideia why?

Sounds related another bug that was resolved with a fix bimg had merged recently. This issue is probably resolved if imaginary is using that newer bimg.
