You should activate the "console" logger and set the debugging flag on.

You'll notice this line to help you understand what's going on:
    Dancer::Logger::core("trying to match `$path' "
          . "against /"
          . $self->{_compiled_regexp}
          . "/");

It appears @values is being created by trying to match $path against the compiled regex. That print will basically tell you what's wrong.

I would personally just download the latest stable, and run it locally with "perl -IDancer-1.2003/lib bin/app.pl" (YMMV) so I could hack at the file, if I need to.
