Don't leave page->tab_label dangling. (gtk_notebook_real_remove): Use

2006-03-20  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtknotebook.c (gtk_notebook_remove_tab_label): Don't leave
	page->tab_label dangling.
	(gtk_notebook_real_remove): Use GTK_IN_DESTRUCTION.
	(gtk_notebook_destroy): Leave the removal of the children
	to the container destroy method.  (#319032, Yevgen Muntyan)

2006-03-20  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtkcombobox.c (gtk_combo_box_remove): Use the existing
	GTK_IN_DESTRUCTION flag, rather than roll our own.
