I had created language-files with django-admin.py makemessages -a
A little bit development later all attempts to create *.po files are failing with:
django-admin.py makemessages -v 3 -a
examining files with the extensions: .html and .txt
Traceback (most recent call last):

I tried it with several file extensions and -ignore patterns. Do you have any hints?
This is due to a bug introduced in Django 1.7.1. You can fix this by updating your Django to the latest version using:
pip install -U django
