Here is a proposed debdiff running the 2to3 step manually, since the
automatic one provided by `build_py_2to3` has been deprecated.
This is probably just a temporary solution while a more general one is
worked either on Debian side by reintroducing `build_py_2to3` somehow,
or, more preferably, a Python3-compatible upstream release is produced.

+Subject: Run 2to3 manually
+
+With the deprecation of 2to3 and the removal of `build_py_2to3`, the automatic
+translation from Python2 to Python3 at build time no longer works. This patch
is
+a manual run of 2to3 while a more general solution is found.
