As a logged in and administrator user, with the toolbar module enabled, I receive the following error on my Firefox error console upon page load:
Timestamp: 3/3/13 1:09:44 PM
Error: TypeError: $(...).once is not a function
Source File: http://local/modules/toolbar/toolbar.js?mj3mjx
Line: 12
Line 12 of toolbar.js is:
$('#toolbar', context).once('toolbar', Drupal.toolbar.init);
When I log-out and become an anonymous user, with the Omega theme enabled, I get this error instead:

Error: TypeError: $(...).once is not a function
Source File: http://local/sites/all/themes/omega/omega/js/omega-mediaqueries.js?mj3mj... 94
Line 94 of omega-mediaqueries.js is:
$('body', context).once('omega-mediaqueries', function () {
Drupal version 7.20
With jquery_update on and off, it doesn't matter what version of jQuery is used. This error is present on 1.4.4 (stock jquery) through 1.8.
