About Dialog crash...

[Enrico <enricoss tiscali it>]

Hi at all!

I have a little problem with GtkAboutDialog and this code:

___________________
void
on_about1_activate (GtkMenuItem     *menuitem , gpointer         user_data)
{
GtkWidget *about;

about = glade_xml_get_widget (xml, "aboutdialog");
  
gtk_widget_show (about);

}
______________________

If I push the X button of the about_dialog for 2  times the entire 
application crashes...where is the mistake?

Many thanks

Enrico
