Hi Frank,

I also had a problem with the sanity check but that came by merging a 
lot of tiles with gdalmerge. A resulting file (~200GB, Geotiff with LZW 
compression) was created but everything I tried on that file failed 
(gdalinfo, gdal_translate, ...). Also all viewing applications failed.

I still have the tiles and I should be abel to recreate the error. What 
information do you need to track down the error?
