OK, I got in touch with Louis.

Reproduction steps:

1) Make sure your LANGUAGE is de, es, fr, id, it, pt_BR, or sl and you have the appropriate language packs installed.
2) Follow the reproduction steps are in comment #11.

Why this bug happens:

In duplicity 0.6.15, a new feature was added to report to frontends
(like deja-dup) whether the backup was encrypted.  This was used in
deja-dup to detect encryption on the fly and thus streamline the UI by
dropping a preference checkbox.

To support older versions of duplicity, deja-dup added some detection
code that relied on parsing a string intended for the user.  Which is
not normally a wise thing to do.  But in 0.6.14 and before, that string
was not marked for translation, so I felt it was safe to parse the
string.

Then, it was discovered that a bug existed in 0.6.15's detection
feature, and I reverted to the string parsing method of detection for
that version.  But in the mean time, that string had been marked for
translation for 0.6.15's release.

So for those languages that translate that string, deja-dup does not
notice the encryption and will continue an encrypted backup as
unencrypted, creating this bug.

The fix:

Implement a slightly different string parsing that does not depend on
the translation for 0.6.15.  I am working on a patch for 22 and will
backport that to 20 once it is approved.

  I'm trying to make a backup to my Ubuntu One online storage with my backup being encrypted.
  Before this error occured, I was making my initial backup when the program returned an error code 302 ("Got status code 302") and aborted when it was close to being finished.

  I'm using
  deja-dup  20.0-0ubuntu3
  duplicity  0.6.15-0ubuntu2
