Fixed problem with missing a message of the error

Before:
&lt;log&gt;&lt;class&gt;error&lt;/class&gt;&lt;href&gt;http://www.example.com/test.html &lt;/href&gt; &lt;/log&gt;

After:
&lt;log&gt;&lt;class&gt;error&lt;/class&gt;&lt;msg&gt;"NetworkError: 404 Not Found - http://www.example.com/pokus.png" &lt;/msg&gt;&lt;href&gt;http://www.example.com/test.html &lt;/href&gt;&lt;/log&gt;
