Starting a new backup results with a AttributeError: 'NoneType' object has no attribute 'name' error ...

[Jean-Philippe LECHÊNE]

Dejadup version: 9.1
Duplicity version: 0.5.16
OS: Jaunty 9.04 i386
Type of backup: on an external (ext4 formatted) usb drive.

Hello,

I've rectenly installed a fresh Jaunty OS on my laptop. I used to use dejadup to make my everyday backup.
It ran find until last week or so.
Then it started to systematically show an error as soon as it tries to make new backup.

Please find below the end of the debugging file produced with DEJA_DUP_DEBUG=1 deja-dup launched with a new backup.

Feel free to ask if you need more information to track down this issue or to point me to the right direction if I've done something incorrect.

Thanks in advance for your help !
