Zend loader error still occuring in 6.x-1.3

When I try to save a content item with a YouTube video, I get the following PHP error: "Fatal error: Cannot redeclare class Zend_Loader in C:\xampp\php\PEAR\Zend\Loader.php on line 31". I am using version 6.x-1.3 of Media YouTube with version 6.x-2.5 of Embedded Media Field. These were working fine together when the site launched in January 2011. I performed updates and now it's broken. I know this is already in the issue queue for version 6.x-1.2, but it doesn't look like it has been fixed or assigned. I tried the solution of changing the reset to TRUE found at http://drupal.org/node/974452, but it did not help.
