> > Property set function gets called when we install the property using g_object_class_install_property, with the default value passed as g_param_spec (http://developer.gnome.org/gobject/unstable/gobject-The-Base-Object-Type.html#g-object-class-install-property), thus setting the WebKit preference to the one specified via g_param_spec. Hence it is not necessary to initialize them separately.

But, what I observed was, *_set functions of properties get called when a new instance of WebKitWebSettings gets created via webkit_web_settings_new. Below is the backtrace,
