[rdiff-backup-users] Warning: expected ... to be a directory but found None instead.

[Alexander Pelzer]

Hello rdiff-backup-users list!

I'm receiving problems after I have deleted an folder in my source 
directory(ies). Here's to mention that I'm using it (v 1.2.8) from a 
Kubuntu machine to backup files on an USB harddisk (therefore the first 
warning). After running rdiff-backup it throws these errors:

Warning: hard linking not supported by filesystem at 
/media/disk/backup/rdiff-backup-data
Previous backup seems to have failed, regressing destination now. 

Warning: expected /media/disk/backup/home/user/bin/folder to be a 
directory but found None instead.
This is probably caused by a bug in versions 1.0.0 and earlier. 

Exception '('home', 'user', 'bin', 'folder')' raised of class '<type

I've seen that this was mentioned here some time ago, but I did not find 
any useful solution ...

Does anyone have an idea?

Thanks in advance
