Stash no results placeholder trickery (untested)

gistfile1.txt

{!-- The URL structure is like this /wiki/{category}/{url_title}/
If I fill in random characters for the {url_title}, {no_results} should be TRUE.
I've verified through the Template debugger that it does indeed return "No results", but the redirect @L91 to the 404 does not work. Is there a problem with the parse order, or is it something with Switchee/Stash?

Thanks!
