[Plugin: WordPress SEO by Yoast] Issues with WordPress SEO and Nextgen

It seems there’s a big canonical issues with Nextgen Galery.

All url created with adding the album/galery shortcode in page content have a bad canonical. All canonical for galery / image url are on the root page.

Example :

http://www.example.com/root-page/galerie/album/galery/

Have canonical on :

http://www.example.com/root-page/

which prevent the search spider to index all albums pages.

I have removed all canonical for page directly form class-frontend.php, but a help to correct it in a more cleaner way would be appreciated
