Invalid foreach errors after upgrade AF 6.1 to AF 6.2-Dev

Been running Advanced Forums with Forum access for a while with success. But I went to try AF 6.2 Dev things seemed to work but my logs started filling up with

Invalid argument supplied for foreach() in /drupal-6.14/sites/all/modules/forum_access/forum_access.module on line 278

The offending area -

* Implementation of $modulename_preprocess_$hook() for forums.
*
* Remove 'post' links from forum page, if the user does not have the
* 'create' permission.
*/
function forum_access_preprocess_forums(&$variables) {
  if (!forum_access_access($variables['tid'], 'create')) {
    foreach ($variables['links'] as $key => $link) {
      if (substr($link['href'], 0, 9) == 'node/add/') {
        unset($variables['links'][$key]);

The line it was complaining about -

foreach ($variables['links'] as $key => $link) {

I rebuilt permissions, deactivated then reactivated Forum Access, deactivated then reactivated Advanced Forum, cleared cache, etc. and still got flooded with this error.

After rebuilding permissions the errors were no longer kicked out for logged in users but anonymous hits are generating this error.

Someone else running 6.2 Alpha 2 of AF is also getting these errors
