[Libguestfs] Error in chunked encoding

[Chris Lalancette]

Hello,
     Oz is a program that does automated installation of virtual
machines.  It is written in python and uses libguestfs pretty heavily
to manipulate ISOs and disks.
     Someone reported an error against Oz here:

https://github.com/clalancette/oz/issues/140

There are some more details in the issue, but it essentially looks
like something happened during libguestfs tar_out:

RuntimeError: /dev/fd/13: error in chunked encoding

Has anyone seen this before?  Any idea what this is about?  If you
want to comment, I would appreciate it if you could comment in the
issue itself.

Thanks,
Chris
