Hi,

Thanks Rich for your advice. I've forgotten it and it's possible.

BTW, please create and run the reproductive small script or interractive
console.
For example, entering your application's directory and hit
script/console
-- script/console start to prompt, then hit
$DEBUG=true
--- and hit (or before enter the code, you need to enter require 'rjb')
Rjb::load('lib/...

It must show the some stack traces or the exception information to the
console, then copy and paste to you mail.

Best regards.
