gtk-directfb-crash

[Moutusi De <moutusi tataelxsi co in>]

Hi All,
I have built gtk with target directfb.
I have installed following pacakages:
1.gtk+-2.18.0
2.atk-1.28.0
3.cairo-1.8.0
4.glib-2.22.2
5.pango-1.26.0
6.pixman-0.12.0
7.DirectFB-1.2.7
8.FreeType 2-9.16.3

Now I am trying to run examples programs thats comes with gtk.While 
running the program one window comes with one mouse pointer and it 
freeze.I ran same
program with gtk- x11 where I get a Hello world message  with proper 
window.I am expecting same thing with gtk-direcfb.
Just for debugging I tried putting one exit(0) before "gtk_widget_show 
(window)" function call.Then I got the following error:

/*****************************************************/
(helloworld:2654): Gdk-CRITICAL **: gdk_drawable_get_colormap: assertion
`GDK_IS_DRAWABLE (drawable)' failed

/*****************************************************

Could anyone please let me know how to resolve this ?

Below is the code for reference.
int main( int   argc,
         char *argv[] )
{
   /* GtkWidget is the storage type for widgets */
   GtkWidget *window;
   GtkWidget *button;

   /* This is called in all GTK applications. Arguments are parsed
    * from the command line and are returned to the application. */
   gtk_init (&argc, &argv);


   /* create a new window */
   window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

   /* When the window is given the "delete-event" signal (this is given
    * by the window manager, usually by the "close" option, or on the
    * titlebar), we ask it to call the delete_event () function
    * as defined above. The data passed to the callback
    * function is NULL and is ignored in the callback function. */
   g_signal_connect (window, "delete-event",
                     G_CALLBACK (delete_event), NULL);

   /* Here we connect the "destroy" event to a signal handler.
    * This event occurs when we call gtk_widget_destroy() on the window,
    * or if we return FALSE in the "delete_event" callback. */
   g_signal_connect (window, "destroy",
                     G_CALLBACK (destroy), NULL);

   /* Sets the border width of the window. */
   gtk_container_set_border_width (GTK_CONTAINER (window), 10);

   /* Creates a new button with the label "Hello World". */
   button = gtk_button_new_with_label ("Hello World");

   /* When the button receives the "clicked" signal, it will call the
    * function hello() passing it NULL as its argument.  The hello()
    * function is defined above. */
   g_signal_connect (button, "clicked",
                     G_CALLBACK (hello), NULL);
/* This will cause the window to be destroyed by calling
    * gtk_widget_destroy(window) when "clicked".  Again, the destroy
    * signal could come from here, or the window manager. */
   g_signal_connect_swapped (button, "clicked",
                             G_CALLBACK (gtk_widget_destroy),
                             window);

   /* This packs the button into the window (a gtk container). */
   gtk_container_add (GTK_CONTAINER (window), button);

   /* The final step is to display this newly created widget. */
   gtk_widget_show (button);

   exit(0);
   /* and the window */
   gtk_widget_show (window);
   /* All GTK applications must have a gtk_main(). Control ends here
    * and waits for an event to occur (like a key press or
    * mouse event). */
   gtk_main ();

   return 0;
}
