I asked about this on the Gtk+ channel, and here are the answers:
* You do not "own" the toplevel window objects, those are
owned by Gtk.
* For those objects we should call `gtk_object_destroy' instead
* JamesH suggested instead that we g_object_ref the return value
of gtk_file_selection_new inside gtk#
So Martin, in Gtk#, what kind of object is giving you this problem, so
we can correctly address this?
The PyGtk people ran into the same issue too.
Alp suggested also that we have a ref metadata flag, so we should
probably use this.
