Can't query entitytype notequal

[fieldguy]

Using the code below, when I change conditionoperator to conditionnotequal, it generates a map exception.  Conditionequal works correctly.  What do I need to change to get entitytype notequal to work?

This is Autocad Map 3D 2011 64 bit.

<CommandMethod("q10")> _
    Sub q_10()
        Dim prjModel As ProjectModel = HostMapApplicationServices.Application.ActiveProject
        prjModel.Options.MarkObjectsForEditingWithoutPrompting = True
        Dim dwgset As DrawingSet = prjModel.DrawingSet
        dwgset.AttachDrawing("any dwg file with text and lines")
        Dim qryModel As QueryModel = prjModel.CurQuery
        qryModel.Mode = QueryType.QueryDraw
        qryModel.Clear()
        Dim qryRoot As QueryBranch = QueryBranch.Create()
        'properties
        Dim propcond As PropertyCondition = New PropertyCondition()
        propcond.JoinOperator = JoinOperator.OperatorAnd
        propcond.ConditionOperator = ConditionOperator.ConditionNotEqual
        propcond.PropertyType = PropertyType.EntityType
        propcond.Value = "TEXT"
        Dim qbproperty As QueryBranch = QueryBranch.Create()
        qbproperty.AppendOperand(propcond)
        qryRoot.AppendOperand(qbproperty)
        qryModel.Define(qryRoot)
        '
        Dim queriedobjids As ObjectIdCollection = qryModel.Execute(dwgset)
    End Sub

We noticed this issue and logged a change request about it. 

I am sorry for any inconveniences.

Thanks.  I found 2 work arounds. 

External query still works - set it up manually and save it.  Then use prjModel.LoadExternalQuery(pathtolspfile).

Or, save and close the queried data and use readdwgfile to make changes (very fast).
