Please pardon me if this is the wrong category. I did not see a "build farm"
category similar.

I am trying to use the ISO openSUSE-Tumbleweed-DVD-i586-Current.iso. I am
extracting it using pycdlib. When I try to open it, I get the error 

pycdlib.pycdlibexception.PyCdlibInvalidISO: Inconsistent Rock Ridge versions on
the ISO!

It seems the CD builder is not complying with the Rock Ridge spec.

If it helps, this is the code in pycdlib which throws the error:
