Bug#842834: diffoscope: building unchanged in jessie-bpo fails

[Mattia Rizzolo]

source: diffoscope
version: 62
severity: minor

If I try to build diffoscope on jessie-bpo as-is, it fails while
starting the tests with:

|copying diffoscope/presenters/html.py -> /build/diffoscope-62/.pybuild/pythonX.Y_3.4/build/diffoscope/presenters
|copying diffoscope/presenters/icon.py -> /build/diffoscope-62/.pybuild/pythonX.Y_3.4/build/diffoscope/presenters
|copying diffoscope/presenters/__init__.py -> /build/diffoscope-62/.pybuild/pythonX.Y_3.4/build/diffoscope/presenters
|make[1]: Leaving directory '/build/diffoscope-62'
|   dh_auto_test -O--buildsystem=pybuild
|	pybuild --test --test-pytest -i python{version} -p 3.4
|E: pybuild pybuild:276: test: plugin distutils failed with: [('/build/diffoscope-62/tests/data/dir_and_symlink_a/lnk', '/build/diffoscope-62/.pybuild/pythonX.Y_3.4/build/tests/data/dir_and_symlink_a/lnk', "[Errno 21] Is a directory: '/build/diffoscope-62/tests/data/dir_and_symlink_a/lnk'"), ('/build/diffoscope-62/tests/data/dir_and_symlink_b/lnk', '/build/diffoscope-62/.pybuild/pythonX.Y_3.4/build/tests/data/dir_and_symlink_b/lnk', "[Errno 21] Is a directory: '/build/diffoscope-62/tests/data/dir_and_symlink_b/lnk'")]
|dh_auto_test: pybuild --test --test-pytest -i python{version} -p 3.4 returned exit code 13
|debian/rules:29: recipe for target 'build' failed
|make: *** [build] Error 25
|dpkg-buildpackage: error: debian/rules build gave error exit status 2

Funnily neither running `dh_auto_test -O--buildsystem=pybuild` nor
`pybuild --test --test-pytest -i python{version} -p 3.4` fails like
that.

Given that this doesn't occur in stretch I assume that's a change done
in something down in the dependency chain.

FTR, this started after commit ea750f17d3e2f3e248294e05d8b66cc901e5fa5c,
which introduced some symlinks within the test suite.
