Solve the following python programming problem given the following code:
def translateVistrail(_vistrail) : 
    ' Translate new DBVistrailVariable based vistrail variables to old
         annotation based type ' 
    global id_scope 
    def update_workflow(old_obj, trans_dict) : 
        return DBWorkflow.update_version (old_obj.db_workflow, trans_dict, DBWorkflow ()) 
def update_operations(old_obj, trans_dict) : 
        new_ops = [] 
        for obj in old_obj.db_operations : 
            if (obj.vtType == 'delete') : 
                new_ops.append (DBDelete.update_version (obj, trans_dict)) 
else : 
                if (obj.vtType == 'add') : 
                    new_op = DBAdd.update_version (obj, trans_dict) 
                    new_ops.append (new_op) 
else : 
                    if (obj.vtType == 'change') : 
                        new_op = DBChange.update_version (obj, trans_dict) 
                        new_ops.append (new_op) 
return new_ops 
vistrail = DBVistrail () 
    id_scope = vistrail.idScope 
    translate_dict = { 
        'DBAction' : { 
            'operations' : update_operations, 
}, 
        'DBGroup' : { 
            'workflow' : update_workflow, 
}, 
} 
    if _vistrail.db_controlParameters : 
        debug.warning (('Vistrail contains %s control parameters that cannot be converted' % len (_vistrail.db_controlParameters))) 
vistrail = DBVistrail.update_version (update_operations, translate_dict, vistrail) 
    vistrail.db_version = '1.0.3' 
    return vistrail 

    
    

    Fix the buggy line: vistrail = DBVistrail.update_version (update_operations, translate_dict, vistrail)

#Here is Python code to fix the buggy line: vistrail = DBVistrail.

vistrail = DBVistrail.update_version (_vistrail, translate_dict, vistrail)
