I am also seeing a similar error with the latest build:
s3sync.rb:500:in `updateFrom': undefined method `closed?' for nil:NilClass (NoMethodError)
from s3sync.rb:387:in `main'
from s3sync.rb:690
I am running s3sync from a cron job with a command like this:
/usr/local/bin/ruby s3sync.rb -r --ssl --delete /home/backups/ bucket.name:/bucket.folder.name/backups
Any ideas?
PS - It would be awesome if you could put this all in a subversion repos so we could keep the code up to date more easily. Or even better you could package it as a Ruby Gem! (Try this for easy gem goodness! : http://drnicwilliams.com/2006/10/11/generating-new-gems/ ).
