slideUp/animate stops working in 1.3.2?


I've been using the following code in an app since jQuery 1.2 and it's
been working fine. However, with an upgrade to 1.3.2 (1.3.1 worked)
this line no longer actually performs:
$('#news-area').animate({opacity: 'hide', height: 'hide'}, 'slow');
also tried
$('#news-area').slideUp();
I've verified that the element exists, and $('#news-area').hide();
behaves just fine. Doing the reverse of show/slideDown works just fine
on the same element.
Is there something in 1.3.2 that could have broken this?
