Quoting Dave Cross <dave at dave.org.uk>:

> Has something changed (deliberately!) in the handling of 404 errors  
> between Dancer2 0.165000 and 0.166000?
> I have a project that is being tested with Travis-CI. The last test  
> that used 0.165000[1] worked fine, but (after a few weeks not  
> working on the project) the next test run used 0.166000[2] and  
> failed on two tests[3] that generate 404 errors.
> I updated my local copy of Dancer2 and found I could reproduce the  
> problem in the web app. The problem seemed to be that the app was  
> always trying to use views/404.tt (which didn't exist) instead of  
> using public/404.html if it can't find views/404.tt - which was the  
> old behaviour.
> Looking through the Changes file, it seems that it might be related to this:
>     * GH #1093, 1095: Use a dynamic TT2 INCLUDE_PATH to allow relative
>       views with relative includes; fixing regression introduced by #1037.
>       (Russell Jenkins)
> But I haven't had time to investigate further.
> I've fixed the problem by adding a views/404.tt file to the project.  
> But I think that's just a workaround.
> I plan to dig a little deeper into the problem later in the week,  
> but I thought I'd mention it here first in case anyone had any  
> insights that could save me some time.

Update: Looks like 0.166001 (released this morning) fixes this problem.
