Dear Maintainer,

I can unzip some isos, but I have one iso [1] that I cannot unzip/test.
It works fine with isomaster and mount, so I assume this is a bug in 7z.

   * What led up to the situation?
Attempted to extract and/or test iso.[1]

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Effective: extracting other isos with 7z, extracting this iso [1] with
isomaster and a loopback mount.
Ineffective: extracting this iso [1] with 7z.

   * What was the outcome of this action?
Error: openSUSE-12.1-NET-x86_64.iso: Can not open file as archive

Thanks,
Jayen
