tabs() causes error when no UL available

If #some_el does not contain a UL the following will cause a javascript error:

$('#some_el').tabs({ ... });

-- snip --

Error: c has no properties

Source file: http://cake_elan.apollo/js/lib/jquery-1.2.6.js

Line: 662

-- snip --

The failure occurs in _tabify() on the line with:

$.data(a, 'load.tabs', a.href);

The following is necessary if #some_el may not have a UL:

if ($('#some_el ul').length) { $('#some_el').tabs({ ... }); }
