354 * non-working selections and crashes. Removing a widget from its container
355 * implies unrealizing it and all its child widgets; this triggers the bug if

357 * workaround, this function walks through the widget subtree before removing
358 * and disclaims the selection from all GtkEditable widgets found.
360 * A similar workaround may be needed for gtk_widget_reparent(); currently it
361 * is not necessary because Sylpheed does not use gtk_widget_reparent() for
362 * GtkEditable widgets or containers holding such widgets.
