images for wpsc-products not showing

seems there is some in 2.1.5 and the images do not show for wpsc products.

in sf.php there is the check:
if($post_type == “wpsc-product”)

which is not working as post_type is not set.
used a $post_type = get_post_type( $pst->ID ) just before

has anyone experienced this?
