Warning: filesize(): stat failed for s3 error when a bucket policy is added

Hi,

Thanks for implementing this module and it works great until I add a bucket policy to restrict my Amazon s3 content from hot linking. I added a bucket policy to allow the files to view when referring only from my website. (I had to add an 'allow' and 'deny' statements to the policy). But after adding the policy, when I try to upload a file from Drupal, I get an error Warning: filesize(): stat failed for s3 error.

I confirmed this by removing the bucket policy and uploading a file. It didn't give any error. Could anyone help me to resolve this issue?

Also I noticed that it doesn't give any error when I remove the "deny" statement from the policy. But then anyone can access my S3 content.

Please help.

Thanks
