[Libguestfs] error/crash on mount

[http_error_418]

Hi,

I am having issues with libguestfs; I am unable to mount a disk either
from cli or via python bindings. This was working previously, but in
order to have access to python3.5 I am trying to upgrade from Debian
8/Jessie to Debian 9/Stretch. Unfortunately the libguestfs error is
getting in the way. Output of libguestfs-test-tool is attached as per
libguestfs.org help.

My current environment:

aphrodite at cleopatra:~$ uname -a
Linux cleopatra 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u3 (2017-08-06)
x86_64 GNU/Linux
aphrodite at cleopatra:~$ /usr/local/sbin/libvirtd --version
/usr/local/sbin/libvirtd (libvirt) 3.1.0
aphrodite at cleopatra:~$ /usr/bin/guestmount --version
guestmount 1.34.6

Please let me know if there is a way I can continue in Stretch - if
necessary I can roll back to Jessie but I really want to get everything
working in Stretch if I can.

Thank you in advance for your time,
