ArcObjects - Error accessing Feature Shape in a console application when using QueryFilter with SubFields

I have the following error when I try accessing the Shape of a Feature in a console application when using a QueryFilter with SubFields.  I am using ArcObjects SDK v10.3 and Visual Studio Express 2012.

 

The element '{http://schemas.microsoft.com/windows/2005/02/color/WcsCommonProfileTypes}Text' is used but not declared in DTD/schema.
The thread '<No Name>' (0x12f8) has exited with code 0 (0x0).

 

The Exception is thrown when I do IGeometry geometry = feature.Shape; in the following code.

 

However if I comment the line where I declare queryFilter.SubFields = "CD_CS_FRA, NOM_OFFCL_CS_FRA";  there is no error.

 

Edit: Using the debugger I can see this:

 

 

using System;
using System.Collections.Generic;
using System.Text;
using ESRI.ArcGIS.ADF;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Geometry;
using ESRI.ArcGIS.esriSystem;
