GDAL statistics take into account the nodata value (more exactly pixel whose 
value equals the nodata value are ignored from the statistics). That might 
explain the differences regarding the min, if 0 was the nodata value. But you 
also get differences for the max value

Can you paste the output of gdalinfo on such a file ?
