The following piece of code seems to solve the problem. Actually I used 
the same code when I hade the same problem with 1.5.0PR.

Current version of method in Zend_Loader (1.5.2) which makes my app go 
bonkers:

   public static function isReadable($filename)
   {
       if (!$fh = @fopen($filename, 'r', true)) {
           return false;
       }

       return true;
   }

My version, which keeps my app happy:

   public static function isReadable($filename)
   {
       if (@is_readable($filename)) {
           return true;
       }

       $path = get_include_path();
       $dirs = explode(PATH_SEPARATOR, $path);

       foreach ($dirs as $dir) {
           if ('.' == $dir || '..' == $dir) {
               continue;
           }

           if (@is_readable($dir . DIRECTORY_SEPARATOR . $filename)) {
               return true;
           }
       }

       return false;
   }
