Steps to Reproduce

Calling Identify on attached file fails

using System;

namespace imageTest
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                var img = SixLabors.ImageSharp.Image.Identify(@"5acshwaw6agp3q6aoaofe5wvj4kvqcq4.jpg");
                if (img != null)
                {
                    Console.WriteLine("Succes!");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
    }
}

Doing Load on same image succeeds.
