As I cannot reopen this issue (which properly does not make sense anyway) have I opened a new Bug #1294201 which explains the issue again how I still experience it even with duplicity including bug fix provided for this issue.

Any hiccup in an upload, which is not uncommon with Ubuntu One, will cause a backup failure. Usually, a hiccup will just cause a retry. But because of this bug, retries will always fail. [Test Case] Make a large backup to Ubuntu One. Eventually, you're likely to hit a 400 Bad Request error. [Regression Potential] The only change is in the Ubuntu One backend. So regressions will be limited to that. [Original Report] On Raring using deja-dup to backup to Ubuntu one, when I add a particular git repository to the folders to backup and then start the backup, the process sits for some minutes at the start of the upload operation and then fails with a popup "Backup Failed. Giving up on request after 5 attempts last status 400 bad request". The progress bar does not get started as far as I can see. While it is saying that it is uploading I can see in System Monitor that data is being continuously sent, but after the failure there are no new files on U1. By a process of elimination I determined that it is the objects directory (which itself contains a large number of subdirectories each containing a number of small files) that is causing the problem. I attempted to determine whether it was a particular file or folder that was causing the problem but it seems not to be consistent. I thought that I had found a particular subfolder causing the problem, I cleared .cache/deja_dup, and then it accepted that folder. However when I then put back the rest of the subfolders it failed again. I copied the complete git repository to another machine (running up to date Ubuntu 12.04) and backing up from there (to a different U1 account) deja_dup has no problems. I also notice that on Raring it always takes a long time in the verification phase even when only a trivial change has been made. It is as if it is downloading the whole repository, but whether that is a related problem I do not know.
