I have tested duplicity from Natty Proposed Repository and it did fix the bug. Works fine.
I ran: https://bugs.launchpad.net/ubuntu/+source/duplicity/+bug/487720/+attachment/2159465/+files/test.sh and got the message: Yay! We didn't hit the bug!
Before the upgrade of duplicity from the proposed repository I ran the same test and I got the message: Guh! We hit the bug! so I was able to reproduce the bug.
