[Grizzly(Francis Smit)]

I found this first on oneiric but it has continued on Precise

1).

root@rakbat:~# lsb_release -d
Description: Ubuntu 12.04 LTS

2).

root@rakbat:~# dpkg-query -W deja-dup duplicity
deja-dup 22.0-0ubuntu2
duplicity 0.6.18-0ubuntu3

3).

grizzlysmit@rakbat:~$ cat /tmp/deja-dup.gsettings

4). it's too long to add here as 1000 lines scrolls off the term I have attached it bellow

5). the error message I normally get in the gui is:
