locally disabling SIG{__WARN__} did the trick,

eval {
   local $SIG{__WARN__};   
   $ok = 1;

Based on this thread:  http://www.perlmonks.org/?node_id=51097

But perhaps a better way is to update Dancer::Route::execute(), to check if we're inside an "eval" block, and if so - not "take over" and show error 500 ? (the "eval" implies that the programmer is aware of the possible failure and wants to handle it?)
