I've been reading the Turbogears documentation over the past days, and
will now dive in more into the code you made.

I updated to the latest kallithea-tg commit (34d3039), installed the
development version of crank (448550f) and tg2 (25f5017) via 'python
setup.py develop' in my virtualenv, then ran 'python setup.py develop'
in kallithea, and 'paster serve development.ini' as I had been doing
before. However, I get the following error:

$ paster serve development.ini

Am I missing something?
If I update to the previous kallithea commit, I don't see this issue.

Thanks,
