    Fix for bgo#582491 - Strange message table behavior with Evolution
    
    Note that this only handles the most extreme problem found - incoming
    mail when Evo is not focused causing Orca to no longer provide access
    to the app with focus. The within-Evo issues are due to bgo#483452
    which was filed against Evolution in October 2007 and which has not
    even been triaged by the Evolution maintainers. :-(
