title: Glide load thumbnail not working
body: <p>I'm using Glide to load thumbnail from videos but it doesn't seem to be working on my app. The ImageView is just empty for some reason.</p>
  
  <pre><code>Glide.with(context)
              .load(url)
              .asBitmap()
              .thumbnail(0.1f)
              .diskCacheStrategy(DiskCacheStrategy.ALL)
              .into(target);
  </code></pre>
  
  <p>I added a listener, so I can figure out what is wrong but the Exception thrown is null.</p>
  
  <p>I tried using ThumbnailUtils using the same url because I thought there might be something wrong with it but the thumbnail loads fine.</p>
  
  <p>Anyone experiencing the same? I'm using a Nexus 7 (6.0.1)</p>
