Illegal division by zero at /usr/bin/mysqltuner line 6099

Using the Debian Bookworm version of mysqltuner, 1.9.9, which is currently the latest version, in a Docker container via Molecule run using GitLab CI, results in this failure:

            (F) You tried to divide a number by 0.  Either something was wrong in
            your logic, or you need to put a conditional in to guard against
            meaningless input.
        Uncaught exception from user code:

MariaDB is running in the container, any suggestions regarding how I could try to debug this?
