Upload/browse area doubles thumbnails

Somewhere in the 2.x series of Wordpress, my file uploads started doubling up - I see double thumbnails for every image I upload (see http://www.cricalix.net/~dhill/wordpress-double-thumbs.jpg). The hyperlinks for each thumbnail are identical.

This looks, to me, to be a problem down in upload-functions.php, in the wp_upload_tab_browse() function. It appears to get double attachment entries for any given post.

Tracing the SQL executed:
SELECT SQL_CALC_FOUND_ROWS posts.* FROM posts LEFT JOIN postmeta ON posts.ID = postmeta.post_id WHERE 1=1 AND (post_type = 'attachment') ORDER BY post_date DESC LIMIT 30, 10

returns double entries for each post, and thus generates a doubled count for the next query that gets executed (the found_rows() query).

If I mod the loop in that function, so that it keeps track of the last ID it saw:

if ( have_posts() ) : while ( have_posts() ) : the_post();
if (get_the_ID() == $last_id) { continue; }
$last_id = get_the_ID();

the output to the browser is what I expect. However, I can't believe that Wordpress is this borked, so it's got to be something in my setup -- or one of the upgrades didn't update some of the schema properly?

I've only got the Spam Karma plug-in, Lightbox plug-in, post levels and the usual moderation ones enabled - no plug-ins relating to uploads at all.
