 450  * GtkEntry (in all GTK+ versions up to and including at least 1.2.10).
 451  *
 452  * The problem is that unrealizing a GtkText or GtkEntry widget which has the
 453  * active selection completely messes up selection handling, leading to
 454  * non-working selections and crashes.  Removing a widget from its container
 455  * implies unrealizing it and all its child widgets; this triggers the bug if
 456  * the removed widget or any of its children is GtkText or GtkEntry.  As a
 457  * workaround, this function walks through the widget subtree before removing
 458  * and disclaims the selection from all GtkEditable widgets found.
 459  *
 460  * A similar workaround may be needed for gtk_widget_reparent(); currently it
 461  * is not necessary because Sylpheed does not use gtk_widget_reparent() for
 462  * GtkEditable widgets or containers holding such widgets.
