Notice: Undefined property: stdClass::$subject in zen_process_block() (line 458 of /zen/template.php

Issue Summary

So I added:

function zen_process_block(&$variables, $hook) {
$variables['title'] = '';
// Drupal 7 should use a $title variable instead of $block->subject.
if(isset($variables['block']->subject)) {
$variables['title'] = $variables['block']->subject;
}
}

Sorry for not submitting a patch. I'm really busy right now.
