I'd prefer to pass the logger object directly with App.config['excepsion_log'], then it can also be configured as a user likes.
Example:
@exception_logger = Logger.new('/dev/null')

if App.config['exception_log'] then
raise CucaException, "exception_log needs to be kind of Logger" unless App.config['excepion_log'].kind_of?(Logger)
@exception_logger = App.config['exception_log']
end

Very good suggestion. Implemented with commit 61d9c10
