#67 udf/tools/chkudf segemntation error with tag 266

udf/tools/chkudf runt on an IOmega tape drive crashed.
This tape contain a filesystem generated some month ago with mkudffs, and mofied by mounting/unmounting the filesystem, on a debian etch 64.

Linux 2.6.18-4-amd64 #1 SMP Fri May 4 00:37:33 UTC 2007 x86_64 GNU/Linux

So, I added some printf to have additional information.

Note that the dump contains
* 4 timestamps (12 bytes fields baginning by 78 10 d7 07).
* Linux in ASCII at end of dump.

Note also than when the filesystem is mounted big files cannot be written (1Gb file size limit), and that writing some files are denied randomly.

All is here after:
