[Debian-med-packaging] Bug#1130357: sniffles: autopkgtest failure with Python 3.14

[Graham Inggs]

Source: sniffles
Version: 2.6.0-1
Severity: important
Tags: forky sid
User: debian-python at lists.debian.org
Usertags: python3.14

Hi Maintainer

The autopkgtests of this package will fail once Python 3.14 is the
default version in Debian.  I've copied what I hope is the relevant
part of the log below.

Regards
Graham
