There's something really weird going on here with your system.
Could it be that /var/tmp is not readable?
Tomas already suggested doing this:
rm -rf /var/tmp/.guestfs-*
then try to run libguestfs-test-tool again. If it still doesn't work,
have a look at the permissions of files in /var/tmp/.guestfs-0 or if
you see any SELinux audit messages.
