Ömer, Is it really a new problem ? Looking at the history of the driver and the error message, I've the feeling it is not a new one.
You'd better open a Trac ticket and attach the dataset that causes the error. You could also check if you get the same issue with the dataset used in the GDAL automated test : http://download.osgeo.org/gdal/data/aig/nzdem.zip Best regards, Even PS : please avoid sending private email and add gdal-dev in CC.
