s3cmd sync -v -skip-existing /home/bubba/backups/pics/ s3://backups.bubba.net/bubba/pics/

This command always says there is 1 remote files to delete like so:

INFO: Summary: 135 local files to upload, 1 remote files to delete

What file is it talking about? It seems to be talking about the dir entry, because even if it's a new empty dir, it says it. It uploads the files ok.
