[Duplicity-talk] ftp resume fails

[edgar . soldin]

there is a ftplicity user experiencing the issue below. I advised to 
update the duplicity version from 0.5.09 to 0.5.17 (not 0.5.18 because 
of waitpid bug) ... any further ideas? ticket is here:
http://is.gd/24LfS

Is there any way to tell the ftp backend how to handle resuming?

thanks ede
