Hi!

While rebuilding the python related packages against the Python 3.15
version we found that gcovr fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4855550/

 From the log, the error seems to be:
    dh_auto_build -i -O--buildsystem=pybuild
I: pybuild plugin_pyproject:142: Building wheel for python3.14 with
"build" module
I: pybuild base:385: python3.14 -m build --skip-dependency-check

	PYTHONPATH=src $py -m gcovr --version; \
done
/bin/sh: 2: python3.15: not found

It looks like the problem is that gcovr build-depends on python3, and
should instead build-depend on python3-all, so that all supported
versions get installed.

Setting the severity to important for now. Once Python 3.15 is released
and later added to python3-defaults, this bug will become release
critical.

We believe that the bug you reported is fixed in the latest version of
gcovr, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1149527@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
