[Gdal-dev] Error propagation from GDAL.Dataset.GetGeoTransform() in C#

[yonil]

I'm trying to use the following code to detect a possible error caused 
by the GetGeoTransform() call, but it reports no error has occurred, and
does not raise an exception.

Making this call on the same dataset from native C code returns 
CE_Failure from GDALGetGeoTransform().

Here's the C# snippet:

_dataset.GetGeoTransform(temp); // returns normally with default values
OSGeo.GDAL.CPLErr err = Gdal.GetLastErrorType();
if (OSGeo.GDAL.CPLErr.CE_None != err)
{
     throw new ApplicationException("GetGeoTransform() failed.");
}

Am I doing anything wrong, or is it somehow a problem with the C# 
bindings? I've built the C# bindings from the GDAL v1.5.3 release, 
running on Win32.

I've uploaded a small C# project with a sample dataset that is causing this
to occur.
