[Box Backup-dev] ProtocolUncertainStream error

[Peter Jalajas, GigaLock Backup Services]

Hi all,

I'm experimenting with boxbackup running on an amazon ec2 ubuntu image
directly into s3 using jungledisk plus/fuse.

It worked great for hours for my 40GB test client, but
now I'm getting this every minute or two (/var/log/messages,
ExtendedLogging=yes):

Any help to make this work would be appreciated.
