Other information:
An exemple to show you the problème try it on Windows with Visual or DevC++. 
It shows a dialog box which is created in another thread :

#include <stdlib.h>
#include <gtk/gtk.h>
#include <windows.h>

/* Dialog message */
void msg(GtkWidget *window){
	GtkWidget *dialog;
	
	gdk_flush();
	gdk_threads_enter();
	dialog = gtk_message_dialog_new (GTK_WINDOW(window),
			GTK_DIALOG_DESTROY_WITH_PARENT,
			GTK_MESSAGE_INFO,
			GTK_BUTTONS_OK,
			"OK");
	gtk_dialog_run (GTK_DIALOG (dialog));
	gtk_widget_destroy (dialog);
	gdk_threads_leave();
}

/* test thread */
void *test(void *data){

	/* Do something ... */
	
	/* Shows final info */
    msg(data);
	
    return(NULL);
}

/* test callback */
void test_callback(GtkButton *button, GtkWidget *window){
    g_thread_create(test, window, FALSE, NULL);
}

/* window with 2 buttons */
GtkWidget *create_window(){
    GtkWidget *window, *button1, *button2, *hbuttonbox;
    
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);   
    g_signal_connect(GTK_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), 
window);
    
    hbuttonbox = gtk_hbutton_box_new();
    gtk_widget_show(hbuttonbox);
    gtk_container_add (GTK_CONTAINER (window), hbuttonbox);
    
    button1 = gtk_button_new_from_stock ("gtk-quit");
	gtk_widget_show (button1);
	gtk_container_add (GTK_CONTAINER (hbuttonbox), button1);
	g_signal_connect(GTK_OBJECT(button1), "clicked", G_CALLBACK(gtk_main_quit),

	button2 = gtk_button_new_with_label("test");
	gtk_widget_show(button2);
	gtk_container_add(GTK_CONTAINER(hbuttonbox), button2);
	g_signal_connect(GTK_OBJECT(button2), "clicked", G_CALLBACK(test_callback),

	return(window);
}
