The effect system used Listeners on property nodes to get the values for shader uniforms. These listeners get deleted by an osg thread causing access to freed memory when this happens while the main thread calls fireValueChanged. This patch changes the update method to polling for scalar properties. This isn't 100% threadsafe, too. But at least it does not crash anymore.
