hey, what ever I do after running "python3 letterpress.py path_to_press_folder" I get:

2014-09-15 18:52:40,890 - INFO - Build site
Traceback (most recent call last):
  File "/home/tester/src/env/bin/letterpress.py", line 869, in <module>

  File "/home/tester/src/env/lib/python3.4/codecs.py", line 896, in open
    file = builtins.open(filename, mode, buffering)
FileNotFoundError: [Errno 2] No such file or directory: '/home/tester/src/press-folder/templates/tags.html'

and all data in press_folder gets completly deleted... I remember that it worked about half an year ago.. maybe this is related to some changings in python3?
