I'm not exactly sure what's wrong.  There are two things you
can try:

(1) Upgrade to a later supermin.  The latest version is 5.1.16, which
is available here:

https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/

It is also much faster than 5.1.10.

(2) With 5.1.16, if it still doesn't work, strace it, and let us see
the full strace.log:

strace -o /tmp/strace.log -s 1024 \
    supermin5 --build -f ext2 -v -v -v /usr/lib64/guestfs/supermin.d \
        -o /tmp/appliance.d
