 Hey, guys.

 i found this when writing a hotel search, where you can search by stars,
 which is actually a custom field.

 So I created a little search script using WP_Query, which is now
 supporting "meta_query" since WP 3.1.

 But if there are 0 stars set, the meta_value is ignored.
 This is because of what's happening in '''meta.php on line 461''', where
 the actual value "0" fails the !empty() condition.

 Hope, this helps. Greetings from Germany!

 (PS: This is my first bug report, so please excuse me, if I have done
 something wrong)
