Fails to return 404 at specific URLs
`workshops/person/example` should return 404, returns 500 instead.

Fix:

``` git
-    url(r'^person/(?P<person_id>[\\w\\.-]+)/?$', views.person_details, name='person_details'),
+    url(r'^person/(?P<person_id>\\d+)/?$', views.person_details, name='person_details'),
```
