[Plugin: Category pagination fix] Simply not fixing the problem

Installed the plugin as usual, but it has made no difference to how the paging behaves when using categories. The query i am using seems to be simple enough :
<?php query_posts( 'category_name=News&posts_per_page=5' ) ?>

Also, a PHP Notice is being displayed : Undefined index: name in…… which is referring to the following line :
<?php if ($query_string['name'] == 'page' && isset($query_string['page'])) { ?>
I would assume this is something to do with the value of $query_string being passed in?

Hope this helps
