Mime types were not being detected as the image does not have a file at /etc/mime.types - see https://github.com/s3fs-fuse/s3fs-fuse/blob/v1.89/COMPILATION.md. This was causing all files to be uploaded with a mime type of application/octet-stream. So I installed mailcap to provide mime types, and now files are detected correctly.
