This is geoserver 1.7.4, using the kml reflector, rendering a polygon layer, with format_options=kmplacemark:true;kmscore=0;. A custom description.ftl template is in place for the layer. The descriptions are included in the placemarks when kmscore=100 (ie. the entire polygon is rendered as a kml placemark) but with kmscore=0 (ie. point placemarks over top of a raster groundoverlay), the placemarks do not include the description (ie. the <description> entity doesn't exist in the output kml). This exception is thrown in this case:

This exception is not thrown in the kmscore=100 case (full polygon placemarks), and the descriptions are included properly. I'm unable to replicate the problem on my development setup, so I can't debug in to find out what exactly is null, I was hoping someone with more experience might have seen this before or have an idea why it might be occurring?
Thanks,
