There is some material difference between /usr/bin/python and a python.org <http://python.org/> binary installation of Python 3.5.  This demonstrates the same crash using small C extension that exports a function that calls DCSGetTermInRange.

The 2.7 framework build on python.org causes the same crash, a local unix build of 3.5.2 doesn’t. As this isn’t a PyObjC issue I won’t investigate this until after the next release.

The good news w.r.t. that release: I just finished my first pass through the entire testsuite on 10.12 and fixed all issues w.r.t. metadata. The next step toward a release is to perform testing on older OSX release to ensure I didn’t introduce issues there.
