Comment 2 for bug 637020

<mdz> bdrung: bug 637020 looks pretty straightforward; ubuntu-iso is a trivial wrapper around isoinfo and doesn't attempt to parse any command line options
<ubottu> Launchpad bug 637020 in ubuntu-dev-tools (Ubuntu) "ubuntu-iso crashed with isoinfo in extract()" [Undecided,Confirmed] https://launchpad.net/bugs/637020

<mdz> it should just exit nonzero rather than crash
 a --help option could be added, but it would be minimal (there is already a man page which explains the lack of options)
