Zwave breaks 0.43

I started with a fresh install of Hassbian for 0.43. However when I install zwave by either the Hasbsian script or manually, after I restart, hass refuses to load. I get no error in the log but loading via the terminal produces these logs.

(homeassistant) homeassistant@hassbian:/home/pi $ hass Traceback (most recent call last): File "/srv/homeassistant/bin/hass", line 7, in <module> from homeassistant.__main__ import main File "/srv/homeassistant/lib/python3.4/site-packages/homeassistant/", line 20, in <module> from homeassistant.util.async import run_callback_threadsafe File "/srv/homeassistant/lib/python3.4/site-packages/homeassistant/util/", line 17, in <module> from .dt import as_local, utcnow File "/srv/homeassistant/lib/python3.4/site-packages/homeassistant/util/", line 8, in <module> import pytz File "/srv/homeassistant/lib/python3.4/site-packages/pytz/", line 33, in <module> from pytz.tzinfo import unpickler File "/srv/homeassistant/lib/python3.4/site-packages/pytz/", line 4, in <module> from bisect import bisect_right File "/usr/lib/python3.4/", line 90, in <module> from _bisect import * UnicodeDecodeError: 'utf-8' codec can't decode byte 0xef in position 79: invalid continuation byte

If I don’t install zwave everything works fine, any help would be greatly appreciated.
