(4.5 regression) Advanced search address tab won't expand if country not selected in address editing

To replicate on demo
http://d45.demo.civicrm.org/civicrm/admin/setting/preferences/address?reset=1
ensure country is deselected in address editing section
(I tested with state province selected - not sure if it matters)

At
http://d45.demo.civicrm.org/civicrm/contact/search/advanced?reset=1
address accordian will not open

If you have debugging on fb gives a backtrace - I've lost it but the key part is

$controlField = $this->getElement($control);
$targetField = $this->getElement($target);

fails when it tries to retrieve the non existent country element

• go to localization > address settings
• uncheck Country in the address fields
• clear caches
• type "adam" in the quick search box and hit return (i.e. don't select anyone)
• get an error
