title: Amazon S3 Access Denied only in CopyObject
body: <p>I'm upload files from nodejs script and when I try to copy object I'm getting Access Denied error, if I try to delete the object or to get it  - there is no problem and it success.</p>
  
  <p>Is there anything spacial in the CopyObject?</p>
  
  <pre><code>params = {
       "Bucket": "buacket-name",
       "CopySource": "source-path/object.txt",
       "Key": "source-path/object2.txt"
  };
  
  s3.copyObject(params, function(err, data)); // With a function for success or error.
  </code></pre>
  
  <p>Thanks.</p>
