Comment(by dd32):

 The query var is being filled with "empty", The field in question is
 designed to query posts based on a specified list, If the list is empty,
 then its not being used.

 Instead, You need to not call get_posts() or whatever if you know you dont
 want to retrieve posts.

 If you're hooking into WP_Query for the main post request, you need to
 modify the query earlier to not run most likely.

 If you need any help on those, i'd suggest the wp-hackers mailing list
