Infinite gtk warnings when I right click on the icon

From this tuto:

#include <gtk/gtk.h>

int main( int argc, char *argv[])
{
  GtkWidget *window;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_widget_show(window);

  gtk_main();

  return 0;
}

I run the executable and right click on the icon,then infinite warnings(the same) reported:

GLib-WARNING **: g_main_context_check() called recursively from within a source's check() or prepare() member.

GLib-WARNING **: g_main_context_prepare() called recursively from within a source's check() or prepare() member.

GLib-WARNING **: g_main_context_check() called recursively from within a source's check() or prepare() member.

....

Anyone knows how to fix this warning?

UPDATE

This problem also exists with gtk-demo , is it a gtk bug? Can someone verify that?

Platform: windows XP

UPDATE2

I found someone had the same issue:

This is a bug in GTK that has been around for quite some time. It is indeed a Windows-only bug. The bug was reported in September 2008. It's still unresolved, but the good news is that there has been some activity last week (including a proposed patch). So it might get fixed in the next GTK release.
