You don't say how you are measuring memory usage and your measurements may not 
be accurate.  However, you don't free GTK+ dialogs with g_free() as it uses 
reference counting for memory management.  You should normally use 
gtk_object_destroy() on the top level window.

See http://developer.gnome.org/doc/API/2.0/gtk/GtkObject.html for an 
explanation of memory management for GTK+.
