Severity: important
Hi!
While rebuilding the python related packages against the Python 3.15rc2
version we found that pytest-mypy-plugins fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4855925/
In the log, we can see that the calls to subprocess fail, but because
the output of the call is sent to /dev/null, we don't know what caused
the failure. However, given that this seems to be looking at error
messages, it's likely that the new Python 3.15 error messages don't
match the expected ones.

Setting the severity to important for now. Once Python 3.15 is released
and later added to python3-defaults, this bug will become release
critical.
