ruby on rails - Can't start unicorn in production - can't convert Pathname into String (TypeError) -

i have rails 3 (spree) application can start in development not production.

if run bundle exec unicorn -c config/unicorn.rb -d -e development works.

however, bundle exec unicorn -c config/unicorn.rb -d -e production, returns with:

master failed start, check stderr log details

here's unicorn.stder.log file:

upgrading ruby 1.9.3 corrects issue.

see github.com/cjheath/polyglot/issues/2 details.

apparently there issue ruby 1.9.1 , 1.9.2 rvm installs.
