Xlib, thread and gnome

[nik600 <nik600 gmail com>]

hi

i am developing an application with gtk and thread.

I've received some Xlib: unexpected async reply  errors and looking on
the web i've see that i must use this code:

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

/* init threads */
g_thread_init(NULL);
gdk_threads_init();

/* init gtk */
gtk_init(&argc, &argv);

window = create_window();
gtk_widget_show(window);

gdk_threads_enter();
gtk_main();
gdk_threads_leave();

return 0;
}

i've tried to add this code at my application but when i try to
execute it i get a segmentation fault error...

this is the reports of gdb:
