I have verified that this is still a problem (basically 3.6b1).

Fatal Python error: Py_Initialize: Unable to get the locale encoding
Traceback (most recent call last):
  File "/opt/python3.6/lib/python3.6/encodings/__init__.py", line 99, in search_function

EOFError: marshal data too short
Aborted (core dumped)

We should be exiting with an error rather than aborting.
