I ran your original file through a local copy of the KML Parser
Example that you can find here:
http://openlayers.org/dev/examples/KMLParser.html
There's a bit in the resulting page that shows:
Feature: Geometry: null
...
Then after paring your kml back to that shown below I got what seems
correct, namely:
Feature: Geometry: POINT(1.2292789482351385 42.12505809906476),
...
<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://earth.google.com/kml/2.0
">
<Document>
<name>ICC - Fulls 1:25.000</name>
<Folder id="layer 0">

</kml>
