I don't think it's a runtime problem (parsing parameters of my subs) - this errors happens during compilation (perhaps because some of the config parsing happens during compilation in some "BEGIN" block? I seem to remember encountering similar annoyances with Dancer 1 when there were problems in the config file).

Anyway, trying with "perl -d" shows the following stack-trace even before showing the debug prompt.
Maybe you'll spot something obvious that I missed...
