 I am not sure if this is a defect or my incorrect use of query_posts,
 here's the scenario, so someone more experienced can decide :)

 We have a few custom post types on our site, and I have built some filter
 options for them, using query posts to modify the loop where necessary.
 For example, when visiting oursite.com/products/ you see a list of all
 products (query_posts isn't used). If you filter these results, you could
 arrive at oursite.com/products/?reviewer=5 which would show all products
 reviewed by user id 5 (a function converts the reviewer=5 part to the
 proper string needed in the query). It works fine with paging as well, so
 oursite.com/products/pages/2/?reviewer=5 works as expected, if there is a
 2nd page.

 However, I ran into a problem with a special post type. We hold online
 seminars, and I am using the post date to indicate the time of the
 seminar. So I have set a seminar to be published in the future on May 5
 for example, and I have modified the query like this:
 "post_type=webinars&post_status=future&order=ASC"

 This works fine as well, but if you go to oursite.com/webinars/page/2 it
 does not show anything, it doesn't even use the same page template
 (archive-webinars.php), it reverts to index.php.

 It seems to me that this is because Wordpress checks if there are any
 results for the default query when rendering a page. We currently have 5
 seminars which have been finished, and 23 which are in the future. By
 using this string to modify the query:
 "post_type=webinars&post_status=future&order=ASC" we correctly get a list
 of 10 upcoming seminars, but when we go to page 2 wordpress seems to
 revert to index.php because it sees that there is no page 2 for the
 original query since there are only 5 past seminars.

 I am reasonably sure that I am using the query_posts() function well
 because it works flawlessly for post types where the default query is not
 changed, only when someone wants to filter results.

 I hope that was clear, if someone could determine if this was me using the
 query_posts() function stupidly or an actual defect that would in itself
 be helpful :)
