Pagination problem

Great plugin , just have a little problem, i have custom post types , this is how i query them

<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; ?>
<?php query_posts('post_type=photos&post_status=publish&posts_per_page='.get_option('posts_per_page').'&paged=' . $paged); ?>

It works great for the one language but for the other language when i try to open the secong page , http://www.mysite.com/videos/photos/2/ it gives me Page not found error 404… any ideas what am i doing wrong and how to fix it ?
