I am new to TurboGears and have just installed TG2 in a virtual environment. I follow the quick start guide and successfully created helloworld via
paster quickstart
I started the server and switched to a web browser on localhost: 8080
Don't you know this, I immediately get an error message, not a welcome message that the documentation that I should see offers.
Error:
AttributeError: 'AcceptLanguage' object has no attribute 'best_matches'
Here's the trace:

pylons.request.accept_language.best_matches ())) AttributeError: the AcceptLanguage object does not have the best_matches attribute
Did I mess up when I installed it, or is it a problem with TurboGears?
Edit: I created a second project, which I called GoodnightMoon, this time without the Mako template option (which is the only difference between the settings), and I get the same error:
'AcceptLanguage' object has no attribute 'best_matches'
Unfortunately, this question is the only one that I can find using a web search related to this particular error.
Are there any other tips I can use and provide stackoverflow to help answer this question?
Following Michael Pederson's advice below, I explored the i18n. I have an i18n directory with one subdirectory called ru (in Russian, I suppose). I work on systems and browsers in English.
I use what the most current TG2 distribution at the time of this question, v. 2.1.3 and tg.devtools 2.1.x
