"make 'test-stem'" failed for Python 3.4.1

Today with tor-0.2.7.1-alpha-152-g130a9c0 and stem 1.4.1-39-gb605836 I get :

  tutorial_examples...                                 failed (0.04s)
test_compare_flags                                           [FAILURE]

...

Shutting down tor... done

You can re-run just these tests with:

  /home/tfoerste/devel/stem/run_tests.py --tor ./src/or/tor --all --log notice --target RUN_ALL --test test.unit.tutorial_examples
Makefile:6781: recipe for target 'test-stem' failed
make: *** [test-stem] Error 1

pyflakes-0.8.1 is installed, pep8-1.5.7 too

FWIW, with 3.3.5 I do get :

  tutorial.tutorial_examples...                        no such test
