gdalinfo dumps core on NITF file

[ReinerBeck]

Running gdalinfo on the attached file results in a segmentation fault.

The file as such is pretty useless, as there is no image segment in it. However, gdalinfo should not crash. Btw, the crash happens in my application as well when I try to access this file with GDAL.

The GDAL version is 1.6.2 from the Fedora 13 distro. I had the same core with the older 1.6.0 version.

gdalinfo --version GDAL 1.6.2, released 2009/07/31

While this bug exists in the 1.6 branch it appears to be already corrected in 1.7.x and later. At this point I'm not inclined to port modest valued bug fixes all the way back to 1.6.
