FATAL ERROR get_gallery_attachment_ids

Hi!

There is a big problem with this snippet which gives me a fatal error
$attachment_ids = $product->get_gallery_attachment_ids();

I am using latest woocommerce and WPML on my site.

It has worked great until the last update I did on Woocommerce, which was from 2.0 to 2.0.10
