odbc OGRVRTDataSource does not work in layerdefinition as of gdal 1.3.2

[Huub Fleuren]

Hi List,

I have the following OVF file which defines an ODBC (msaccess) 
OGRVRTDataSource.
I'm testing this with gdal 1.3.2

<OGRVRTDataSource>
        <OGRVRTLayer name='kpxy'>
            <SrcDataSource>ODBC:admin/admin at anwb</SrcDataSource>
    <SrcSQL>SELECT k.kp_nr as kp_nr,k.x as x, k.y as y, w.wcode as 
wcode, w.ocode as ocode FROM wwall w, kpxy k WHERE NOT (k.soort LIKE 
'D') and (w.x &gt; 190000) and (w.x &lt; 200000) and (w.y &gt; 500000) 
and (w.y &lt; 520000) and (w.nummer = k.kp_nr)</SrcSQL>
            <GeometryType>wkbPoint</GeometryType>
            <LayerSRS>WGS84</LayerSRS>
            <GeometryField encoding='PointFromColumns' x='x' y='y'/>
        </OGRVRTLayer>
    </OGRVRTDataSource>


ogrinfo test.ovf -sql "select count(*) from  kpxy"
ERROR 4: Update access not supported for VRT datasources.
Had to open data source read-only.
INFO: Open of `test.ovf'
using driver `VRT' successful.
Layer name: kpxytest
Geometry: Point
Feature Count: 1
Layer SRS WKT:
(unknown)
count_*: Integer (0.0)
OGRFeature(kpxytest):0
  count_* (Integer) = 375

I copied the test.ovf into the layer definition. (see complete layerdef 
further)
To my surprise there are no points selected.

I ( sometimes ) get the following error

How can it be explained?. Can i get it to work? Is this a bug?
