Run into this from time to time, you could try disabling backing up of globals and see if it goes away. Possible you have something in the global scope that has a closure as a public property that PHPUnit is trying to serialize between tests.

This will happen if you have nonserialisable objects as globals. Try running with --no-globals-backup or eliminate the global scope you're using (i.e. move things inside the scope of your tests)
