what am I doing wrong

[Wallace Matthews]

Thanks for the suggestion. It works fine if I remove the --write-batch from the command line. 
That should narrow it down for the bug fixer(s). I know that --write-batch works ok when the reference file is on a remote system. 

It means that until there is a fix, I have no use for the local only case. My only purpose for using it was to create delta files that I could then send to remote system(s) to create incrementals.

Do you observe the same behavior without "write-batch"?
