[webkit-gtk] memory leak

[Alberto Mari]

Hi,
i have a problem in my gtk widget. I need reload the single page every 
15 seconds, but libwegtk alloc memory

My example

In main

c_html = webkit_web_view_new();

     WebKitWebSettings *settings = 
webkit_web_view_get_settings(WEBKIT_WEB_VIEW(c_html));
     g_object_set(G_OBJECT(settings), "enable-page-cache", TRUE, NULL);
     g_object_set(G_OBJECT(settings), 
"enable-offline-web-application-cache", TRUE, NULL);
     g_object_set(G_OBJECT(settings), "enable-private-browsing", TRUE, 
NULL);

     webkit_set_cache_model(WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER);

     gtk_widget_set_usize(GTK_WIDGET(c_html), 450, 300);
     gtk_widget_set_uposition(GTK_WIDGET(c_html), 574, 92);
     gtk_container_add(GTK_CONTAINER(canvas), GTK_WIDGET(c_html));
     gtk_widget_show(GTK_WIDGET(c_html));

     webkit_web_view_load_uri(WEBKIT_WEB_VIEW(c_html), urlMeteo);

g_timeout_add(10000, callback, NULL);

gboolean callback(gpointer wk) {


     webkit_web_view_reload(WEBKIT_WEB_VIEW (wk));
       return TRUE;
}
when call callback the memory leak
Why?
the page contain object flash
