This question would be better addressed to the GDAL/OGR mailing list
(gdal-dev at lists.osgeo.org).  I imagine the problem is that the kml file
has a mixture of geometry types in it, perhaps points and lines?  Shapefiles
can only hold one type of geometry - in the above case likely established
by the first geometry written to the file.

You will need to do something like:

   ogr2ogr out_points.shp your.kml -skipfailures -nlt point
   ogr2ogr out_lines.shp your.kml -skipfailures -nlt linestring
   ogr2ogr out_poly.shp your.kml -skipfailures -nlt polygon
