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/ ).
