The constructor "rsvg_new_filter_primitive_component_transfer" does not set a destructor.

The following code corrects the memory leak:
-----------------------------------------------------------------

static void
rsvg_filter_primitive_component_transfer_free (RsvgNode * self)
{
   RsvgFilterPrimitiveComponentTransfer *upself;

   upself = (RsvgFilterPrimitiveComponentTransfer*) self;
   g_string_free (upself->super.result, TRUE);
   g_string_free (upself->super.in, TRUE);
   _rsvg_node_free (self);
}

RsvgNode *
rsvg_new_filter_primitive_component_transfer (void)
{
   RsvgFilterPrimitiveComponentTransfer *filter;

   filter = g_new (RsvgFilterPrimitiveComponentTransfer, 1);
   _rsvg_node_init (&filter->super.super, RSVG_NODE_TYPE_FILTER_PRIMITIVE_COMPONENT_TRANSFER);
   filter->super.result = g_string_new ("none");
   filter->super.in = g_string_new ("none");
   filter->super.x.factor = filter->super.y.factor = filter->super.width.factor =
       filter->super.height.factor = 'n';
   filter->super.render = &rsvg_filter_primitive_component_transfer_render;
   filter->super.super.free = &rsvg_filter_primitive_component_transfer_free;
   filter->super.super.set_atts = rsvg_filter_primitive_component_transfer_set_atts;
   return (RsvgNode *) filter;
}
