GTK编程，右键点击任务栏上图标报错

Fomalhaut

环境是windows xp sp2，gtk-+2.0 version 2.16.6, gcc 3.4.5 (mingw-vista special r3)
运行demo，及自编的程序
最简单的程序如：
#include <gtk/gtk.h>
int main( int argc, char *argv[] )
{
GtkWidget *window;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (G_OBJECT (window), "delete_event",
G_CALLBACK (gtk_main_quit), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 10);       
gtk_widget_show (window);
gtk_main ();
return (0);
}
编译成功，但是在运行时，右键点击任务栏上的程序图标，在console里会报错：
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.

我到处打听，不知有高手知道吗？
PS： google上 我只搜到两条相关信息，怀疑是个bug
