[gdal-dev] Strange behaviour of gdal_translate

Hi list,
I'm trying to convert the attached virtual file into a regular geo-tiff.

Note that the dataset defines both a geo-transform and GCPs but
they have different projections.

After conversion if I call gdalinfo on the result file I get

$ gdalinfo out.tif
Driver: GTiff/GeoTIFF 
Files:out.tif
Size is 22000, 21890 Coordinate System is:
GEOGCS["WGS 84",

The generated geo-tiff has wrong projection info.

Is this a but? 

Is there some rule to determine which geographic information is
authoritative?


Best regards
