Bug#1057604: texext: FTBFS: AttributeError: module 'configparser' has no attribute 'SafeConfigParser'. Did you mean: 'RawConfigParser'?

Package: src:texext
Version: 0.6.7-1
Severity: serious
Tags: ftbfs

Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build:

--------------------------------------------------------------------------------
[...]
dh clean --with python3 --buildsystem=pybuild
dh_auto_clean -O--buildsystem=pybuild
I: pybuild base:310: python3.12 setup.py clean

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202312/

About the archive rebuild: The build was made using virtual machines
from AWS, with enough memory, enough disk, and either one or two
CPUs, using a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks.
