Ok this is enough to generate the issue

	  <script type="text/javascript">
	  //<![CDATA[
	  window.onload=Load_Map

	  function get_icon(type) {
		var color;
		if ((typeof(type)=="undefined") || (type==null)) 
		{ 
		color = "red" 
		} 
		else { 
		color = type 
		}
		var icon = new GIcon();

		icon.image = "$bburl/images/googlemapme/mm_20_"+ color +".png"; 
	

		icon.shadow = "$bburl/images/googlemapme/mm_20_shadow.png";
		icon.iconSize = new GSize(12, 20);
		icon.shadowSize = new GSize(22, 20);
		icon.iconAnchor = new GLatLng(20, 2);
		icon.infoWindowAnchor = new GLatLng(1, 5);
		return icon;
	
	  }
	  
		 	  //]] </script>

As written it saves fine but if I add a vb variable (for example {vb:raw map_type}) then it won't save.
