Relation with post types in search parameters

When specifying a number of post types for a relation, the lightbox paging only 
uses the first selected post type.

What steps will reproduce the problem? (Be *specific*)
1. create multiple posts in 2 or more post types (could be post/page/custom 
type)
2. create a new relation custom field
3. click 'set search parameters' and tick multiple post types so that the 
number of search results will be more than 10
4. save field and add to a post type
5. create a post type with the new relation field
6. click the button to create the relation
7. when the lightbox appears note the pagination links - this will correctly 
show 1 link per 10 results
8. click on the page 2 link or higher

What is the expected output?

You should see the paged results for all selected post types

What do you see instead?

You are shown the results for page X of the first selected post type

It seems that the paging is ignoring the fact that there are multiple values 
for the post_type[] <select> form control and just using the first post type.

Does the problem continue if you disable all other plugins? (plugin
conflicts cause a LOT of problems, so please isolate the problem)

Yes
