Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that genshi fails to build from source [1].

While looking for the fix, I found an unapplied PR upstream that tackles
the problem [2].

I've applied the PR fix in the sandbox [3] to be able to build the
packages that depend on genshi, please consider applying the patch to
support the upcoming 3.15 version.

Happy hacking,
