Bug#1081651: FTBFS with Python 3.13

[Stefano Rivera]

Source: ros-geometry2
Version: 0.7.7-1
Tags: upstream
User: debian-python at lists.debian.org
Usertags: python3.13
Forwarded: https://github.com/ros/geometry2/issues/568

This package failed build from source when test-built against a version of
python3-defaults that includes 3.13 as a supported version.

To reproduce this issue, build against python3-defaults (python3-all-dev etc.)
from Debian experimental.

What's new in Python 3.13:

This bug has been filed at "normal" severity, as we haven't started the
transition to add 3.13 as a supported version, yet. This will be raised to RC
as soon as that happens, hopefully well before trixie.

Thanks,
