+ *
+ * The problem is that unrealizing a GtkText or GtkEntry widget which has the
+ * active selection completely messes up selection handling, leading to
+ * non-working selections and crashes. Removing a widget from its container
+ * implies unrealizing it and all its child widgets; this triggers the bug if
+ * the removed widget or any of its children is GtkText or GtkEntry. As a
+ * workaround, this function walks through the widget subtree before removing
+ * and disclaims the selection from all GtkEditable widgets found.
+ *
+ * A similar workaround may be needed for gtk_widget_reparent(); currently it
+ * is not necessary because Sylpheed does not use gtk_widget_reparent() for
+ * GtkEditable widgets or containers holding such widgets.
