It’s a bug in the theme…

The above change fixes it.

The problem was that it was trying to get a page “foo” under the “project/” section where you would have project = "foo" in your front-matter. But even if that page did not exist under project/ section, it would try to get .Permalink out of that… effectively doing nil.Permalink. Now that .Permalink step happens only if the .GetPage succeeds.
