title: Wordpress: An error occurred in the upload
body: <p>After updating to WordPress 3.5, I started getting the following error when uploading files using the Add Media button as a non-admin user:</p>
  
  <blockquote>
    <p><strong>Error: An error occurred in the upload. Please try again later.</strong></p>
  </blockquote>
  
  <p>The image seems to finish uploading, but right at the end this error message appears.</p>
  
  <p>This doesn't happen for the administrator, only the other roles. I've even tried giving the other role full admin capabilities, but the error still appears.</p>
  
  <p>Is this a bug? Or am I missing something?</p>
