Comment (by fedallah):

 When I replied to the Trac email on this post earlier in the month, I
 figured the list would thread my response to Trac, too. Oops. So here's a
 link to the wp-hackers email about this bug for reference:

 http://comox.textdrive.com/pipermail/wp-hackers/2007-July/013734.html

 Anyway, re: santosj, the get_class() approach fails whenever an object is
 instantiated more than once, and each instance is attempted to be
 registered with the same method. I wrote about this in my message to the
 list earlier this month.

 Example code:

 {{{
 class Foobar {
         var $name;

         function Foobar( $name ){
                 $this->name = $name;
         }

         function hook( $v ) {
                 return $this->name . " Hooked! $v";
         }
 }

 $foo1 = new Foobar("baz");
 $foo2 = new Foobar("quux");

 create_filter( 'the_content', array( &$foo1, "hook" ) );
 create_filter( 'the_content', array( &$foo2, "hook" ) );
 }}}

 $foo1 and $foo2 will have the same class name, and therefore, will be the
 same index in the filter array. So sadly, this solution doesn't work. See
 my post for one which I think has a better shot.

 Also, serialize is big and expensive. I think we should avoid calling it.
