Description

I keep receiving this warning using GDAL (1.6.3 released 2009/11/19 on Ubuntu desktop 9.10) whith GRIB2 files:

gdalinfo file.grb2 "Warning: Investigate Template 4.8 bytes 35-41 Warning: Investigate Template 4.8 bytes 35-41 (...) Warning: Investigate Template 4.8 bytes 35-41 Warning: Investigate Template 4.8 bytes 35-41 Segmentation fault"

The strange thing is that it works fine with some GRIB2 data, like this file[1] but with some other's, from the same source[2], just won't work at all, like this one[3].
