title: openDatabase error at Safari 7
body: <p>I have the following code in my application:</p>
  
  <pre><code>openDatabase('main', '1.0', 'Database display name', 50 * 1024 * 1024)
  </code></pre>
  
  <p>It worked fine until Apple introduced Safari 7. Now it fails with the following exception:</p>
  
  <blockquote>
    <p>SecurityError: DOM Exception 18: An attempt was made to break through
    the security policy of the user agent.</p>
  </blockquote>
  
  <p>Does anybody know how it can be solved?</p>
