I am only seeing this with OpenLayers.Handler.RegularPolygon which
seems to be exactly like
the other handlers in to http://trac.openlayers.org/ticket/1143
this.layer has no properties
[Break on this error] this.layer.renderer.clear();
RegularPolygon.js (line 365) (trunk)
whilst using a done callback, both featureAdded and done callbacks
throw an error
when deactivating a control ( also on 2.5)
