Looks like this is another error I've missed in the builds since we fall back
to the pure Python Namemapper in case of error (relevant build output:
    http://hudson.brokenco.de/job/Cheetah__Next/label=Mac,namemapper=purepython,python=python25/19/console
)

I'll take a look at this this evening if I have the bandwidth :)
