When I click KML in Google Maps save my Saved Places, it saves a 1KB KML file to my hard drive
All I get from ConvertKMLCSV is:
[INFO] Reading KML file...
[INFO] Sorting placemarks alphabetically by name...

Can you open a bug report and attach the kml file that causes the problem? I want to test it on my sandbox.
