This line of code, by the way, seems to answer your question from
earlier today - the way you get a template to render something for you
is to instantiate its View, just like (I think) you're doing here.

Does your template try to determine the URL to "master.css" anywhere?
Whenever, in a template, you say "get the URL of <this>", you have to
make sure that "<this>" can be "traversed" to find where it lives and,
perhaps in this case, what lives inside of it.
