Bug#959647: lasagne: FTBFS: dh_auto_test: error: pybuild --test --test-pytest -i python{version} -p 3.8 returned exit code 13

I am confused.  This bug is filed against
0.1+git20200419.5d3c63c+ds-1, which contains a patch for this exact
problem, but the build logs indicate that the previous version,
0.1+git20181019.a61b76f-2, is being built.
