I'm getting a segfault when destroying the WebView widget in a idle callback.
Piece of code:

...
  g_signal_connect (self,
            "navigation-policy-decision-requested",
            G_CALLBACK (link_cb),
            NULL);
...

static gboolean
link_cb (WebKitWebView             *web_view,
     WebKitWebFrame            *frame,
     WebKitNetworkRequest      *request,
     WebKitWebNavigationAction *navigation_action,
     WebKitWebPolicyDecision   *policy_decision,
     gpointer                   user_data)
{
  const gchar *uri;

  uri = webkit_network_request_get_uri (request);
  if (strncmp (uri, "ascli://remove", 14) == 0)
    {
      webkit_web_policy_decision_ignore (policy_decision);
      g_idle_add ((GSourceFunc) delayed_destroy, web_view);
      return TRUE;
    }

  return FALSE;
}

...

static gboolean
delayed_destroy (GtkWidget *w)
{
  gtk_widget_destroy (w);  <<<<----------- CRASH
  return FALSE;
}

......

I'm putting the WebView inside a GtkVBox
