Same error here.
My code:
$posts = new WP_Query(array(
'post_type' => 'post',
'posts_per_page' => 4,
'paged' => $paged,
'post__not_in' => array_values($ids),
));
The ids in $ids var has no effect. I mean, the posts with the id in the array appear in the result.
I am using version 1.5.8.2 of the plugin. The same line that Leo Caseiro commented (in this version #317) fixes the bug.
