Hi Daniel, Looking at the javadoc for HtmlSelectManyListbox ( http://java.sun.com/javaee/javaserverfaces/2.0/docs/api/javax/faces/component/html/HtmlSelectManyListbox.html ) it looks like it doesn't implement Serializable. Since you are binding to it in a session scoped bean, you must have a reference to it in your bean, then it looks like GAE is trying to serialize the session, which includes your bound instance of that class.
This is all just guesswork based on your stack trace. If it were my code, I would probably try to figure out how to do what I need to do without binding jsf controls in my managed beans.
