tableheader.js: getting "parent has no properties" error after Ahah table replacement. [#213064]

I have a module that does an ajaxForm call to get a new version of the block's page, and then does a .html() call to replace the current blocks table with the new one. Then, of course, I do a Drupal.attachBehaviors on the new table. That is all fine and the javascript table headers show up as expected on the new table. But, as soon as I scroll, I get the following error in Firebug:

parent has no properties
while ( parent.tagName && !/^body|html$/i.test(parent.tagName) ) {
in jQuery 2958

(I got the actual jQuery line and line number by swapping in an uncompressed version of jQuery 1.2.1. It is in the offset function).

I commented out the contents of the tableheader.js file, and the error went away, but I have not been able to track it down more than that.
I have not noticed any actually problems or reduced functionality as a result of this error.

This was originally encountered here: http://drupal.org/node/179937

That was when the blocks table was implemented with disabled regions not showing up on the table. When I was fixing various other issues with tableheader.js, I reverted that by accident thinking I was using a more efficient selector.

Could you do a quick test by swapping out this line at the bottom of tableheader.js?

    time = setTimeout(function () {
      $('table.sticky-header').each(function () { // <- change this line.
        // Force cell width calculation.
        this.viewHeight = 0;
        tracker(this);
      });
      // Reset timer
      time = null;
    }, 250);
