* 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.
