commit ab9a897b688e991a8405cf938dea9d6a2f1ac072
Author: Andreas Kling <andreas.kling at nokia.com>
Date:   Sun Jun 20 19:56:33 2010 +0200

    Unbreak _HB_OPEN_Get_Device() and Get_ValueRecord()
    
    Fixes regression from 5ab1e41c + a1714c84
    "Get" functions should read from tables, not create them.
