This error fires when pressing 'Recreate .htaccess files"
The function drupal_tempnam() seems to be D7 only
Can confirm we are seeing the same error when attempting to select the "Generate .htaccess files in the advagg_* dirs" option from within the "/admin/settings/advagg/config" settings page:
Fatal error: Call to undefined function drupal_tempnam() in ../advagg/advagg.module on line 1425
This issue exists in the 6.x-1.9+5-dev (2012-Sep-05) version of the module. And yes, correct it is a Drupal 7 (and above) API function only: http://api.drupal.org/api/drupal/includes!file.inc/function/drupal_tempnam/7
