[Plugin: NextGEN Gallery] BUG: many Notices while paginating Gallery

We have WP debug enabled on a site we’re developing and NextGen is producing several notices:

Notice: Trying to get property of non-object in /thefullpath/public_html/wp-includes/post-template.php on line 30

That line is about getting the current item’s (post) ID.

Also, after we enabled nextgen permalinks:
PHP Notice: Trying to get property of non-object in /thefullpath/public_html/wp-content/plugins/nextgen-gallery/lib/rewrite.php on line 115

Although those are PHP Notices and are not viewable if wp-debug if off this is weird on how nextgen tries to use several objects wrong…

Edit: I forgot to mention that those notices appear while paginating through a gallery embedded to any page via sortcode either with AJAX or regular pagination.
