Hi again!
Nathan just pointed out on slack two things:
  1) that fix was backported to stable branch and *was* released with 3.2.3
  2) your traceback suggests that you're not using yt installed by 
conda, but rather a source installation.

If you want to use yt that comes with conda could make sure that:
  1) your PYTHONPATH is empty or unset
  2) you're using proper version of python, export 
PATH=<conda_dir>/bin:$PATH should take care of that.

If you want to use yt from source, could you make sure that:
  1) you're on right revision: hg update yt-3.2.3
  2) recompile source: python setup.py build_ext -i

Cheers,
Kacper
