unknown error when backup of files actually starts

Asked by Michael Jackson

Hi
After the programs scans and then starts to actually back up the files it quits with a unknown error. I am using Fedora 13. I tried also running it as sudo deja-dup but I got the error. I also still have, I think, the dialog from the terminal window if that would help. I have removed the files from ccache and it still gives an error. What should I try next?

Okay here is the info from the terminal window when I ran sudo deja-dup. Ps I did run it as a normal user first, just tried this to see if a permission or other problem might be solved
start terminal output
[m-jackson@Oz ~]$ sudo deja-dup

Can you file a bug and include the log file that the bug form tells you how to generate? I'm particularly curious which file seems to generate this problem.

https://launchpad.net/deja-dup/+filebug

I notice you have some interesting include folders, like /sys and /selinux. I'm guessing that some file in one of them is tripping up duplicity.

Can you help with this problem?

Provide an answer of your own, or ask Michael Jackson for more information if necessary.
