Contentless mako.exceptions.CompileException while trying to build a site that worked with blogofile 0.7.1

[mgedmin]

Blogofile 0.8b1 chokes and dies on my website, which used to work fine with Blogofile 0.7.1. What's worse, the error message doesn't even tell me which file it didn't like.

To reproduce:

git clone https://github.com/mgedmin/gedmin.as
cd gedmin.as
git checkout 85b2738
make build

Here's the traceback I get:

env/bin/blogofile build -s website
