[Murray Cumming <murrayc src gnome org>]

commit 5cf223201ece3534ab177e7eaaa75322542e8bec
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu Sep 29 12:18:31 2011 +0200

    Dialog_Choose_ID: Work around a crash in GTK+.
    
    * glom/mode_data/datawidget/dialog_choose_id.cc: Remove the Box_Data_List
    from the parent container (we added it earlier), to avoid a crash, though
    it would be good to fix that properly and generically.
    Bug #660347
