Interesting. That did the trick actually. So this test code... 

     my $test_header = $cgi->header(
         -type => 'application/xml'
     );

     ddump('test_header', __LINE__, $test_header);

     my $another_test_header = $cgi->header(
         -nph => 1,
         -type => 'application/xml'
     );

     ddump('another_test_header', __LINE__, $another_test_header);

...produced the following debug output... 

$test_header_line_673_1 = '';
$another_test_header_line_680_1 = 'HTTP/1.1 200 OK
