Toaster tests have been failing on fedora 40 (this seems reproducible):

I believe the actual error is selenium crashing:

But, later on, we also see:

>           raise RuntimeError(f"Can't initialize toaster. {message}")
E           RuntimeError: Can't initialize toaster. Port 8000 occupied by python3 /home/pokybuild/yocto-worker/toaster/build/bitbake/bin/../lib/toaster/manage.py runserver --noreload localhost:8000
