Version: 2.7.2-1
Severity: normal

Usertags: python3.13

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,

Stefano
