I didn't find nothing relevant in the project's issues or SO, only this question which is basically the very same issue.

The problem seems the absent of where tag from georss namespace.

How to replicate in unittests:

<!--
Description: item point where
Expect: entries[0]['where']['type'] == 'Point' and entries[0]['where']['coordinates'] == (31.1732, 36.9382)
-->
<feed
  xmlns="http://www.w3.org/2005/Atom"
  xmlns:gml="http://www.opengis.net/gml"
  >
  <entry>
   <gml:Point>
     <gml:pos>36.9382 31.1732</gml:pos>
   </gml:Point>
  </entry>
</feed>
