Comment:

 Closed Ticket #16573 as duplicate.

 > In 3.1, you can pass meta_value = '_wp_zero_value'.

 For any developers coming across this, Please do not use it. Yes, It works
 in 3.1 but it's [http://core.trac.wordpress.org/changeset/17088#file2 an
 internal hack only].. You cannot rely on this being there for 3.2.

 using strlen() on [http://core.trac.wordpress.org/browser/trunk/wp-
 includes/meta.php?rev=17170#L423 Line 423] will probably fix this ticket.
