Does not seem to work on Python 3.8

[AlexGustafsson]

Running the example given on the README gives me roughly the following output:

python3 example_application/fuzzing_tests/greeter_fuzzing.py

I'm using Python 3.8 on macOS.

I can't reproduce this locally with Python3.8

Can you give it an other on the current master?
