STEPS TO REPRODUCE

ansible-lint command in our CI container crashes when the following commands are sent

git clone https://our_project.git # done by CI
cd our_project # done by CI
ansible-lint -c .ansible-lint roles/

Desired Behavior

Using the exact same container with the exact same configuration but starting ansible-lint outside the project don't crash (we still have to fix a lot of things)

git clone https://our_project.git
ansible-lint -c our_project/.ansible-lint our_projet/roles/
