[Duplicity-talk] "Bad fd number" with new FTP backend

[daacyy302]

I'm trying to use the new FTP backend to perform a full backup from my 
Linux computer to my Windows box (running FileZilla).  I'm then 
uploading the results to Amazon S3 from Windows.

I used this command line (I know, I know, I'll change it to "-v 9" until 
we get a stable new Duplicity release).

duplicity -v 6 --archive-dir /var/backups/duplicity_archives 
--include-globbing-filelist list --full --short-filenames / 
ftp://address@hidden/

The full backup runs for several hours and then fails with these error 
messages:

Comparing ('root', 'tmp', 'HyperSpec-7-0.tar.gz') and None

As an aside, does this mean that it's trying to delete files on the 
Windows box?  There was only an empty directory there when it started 
the full backup; why would it be deleting files?  Also, I told it to 
store the signatures locally using the --archive-dir switch, so if it's 
trying to delete signatures, it shouldn't be doing it via FTP.
