UI-Tabs: selected option bug with core 1.2.6

Using UI 1.5.1 with jQuery 1.2.3. Tabs plugin is being used with ajax loaded content. Using tabs method which takes options to create tabs object. Options include 'selected' parm to select the second tab (out of 2 total). This works as desired.

Introduced jQuery core 1.2.6r5685. The 'selected' parm no longer appears to work. The page loads, but no content is displayed. If I view the generated source of the page using FireFox and the Web Developer plugin, I can see that the ajax content is loaded correctly, but the "ui-tabs-panel" (which is being targeted via the tab with an id of "tabContent") contains the class "ui-tabs-hide" causing the content to be hidden. If I then click on the first tab, the content is loaded for that tab and displayed to the user; however, the second tab is not active and cannot be clicked.

If I pass a 0 as the default selected, or remove the parm from the options passed, the 0 tab displays correctly and I am able to click on the second tab and its content displays correctly.

I have found a workaround that works.

Broken:

$(document).ready(function(){
  $("#tabs").tabs({remote: true, selected: 1});
});

Workaround:

$(document).ready(function(){
  var tabs=$("#tabs").tabs({remote: true, selected: null});
  tabs.tabs('select',1);
});
