GetStatistics() returns wrong list in Python

[warmerdam]

import gdal
ds = gdal.Open('utm.tif')
print ds.GetRasterBand(1).GetStatistics(1,1)

reports: [0, 0.0, 255.0, 104.44825962611607, 56.757824326870313] but it should report [0.0, 255.0, 104.44825962611607, 56.757824326870313]. That is, an extra zero entry is being returned in the list.

This problem seems to be related to this call in Band.i:

%apply (double *OUTPUT){double *min, double *max, double *mean, double *stddev};
  CPLErr GetStatistics( int approx_ok, int force, 
                      double *min, double *max, double *mean, double *stddev ){
    return GDALGetRasterStatistics( self, approx_ok, force, 
				    min, max, mean, stddev );
  }
%clear (CPLErr);

Note that there are only four return values.

I am using SWIG 1.3.31. This was observed on trunk. I haven't check 1.4.x.

PS. This causes autotest/gdrivers/hfa.py when run against the NG bindings.
