Version information for this bug is hard to come by, since the useful
bit is the version that was actually used for the backup.  But in bug
804484, the user implies that they backed up in Ubuntu 10.10 before
moving to (and trying to restore on) Ubuntu 11.04.

So that would mean duplicity 0.6.10 is the most recent version for which
we have evidence that it can trigger this bug.

Title:
  Crash when restoring data KeyError

Status in Déjà Dup Backup Tool:
  Confirmed
Status in Duplicity - Bandwidth Efficient Encrypted Backup:
  In Progress
Status in “deja-dup” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: deja-dup

  1) Ubuntu 9.10
  2) Deja Dup 10.2-0ubuntu1.1
  3) I expected my backup to be restored
  4) Deja Dup crashed instead.

  I just tried to restore the backup I made, and it crashes repeatedly
  when trying to restore.

  I have it setup to backup my home directory, and tried restoring to
  both the original location as well as a completely different folder.
  Both lead to the same error message.
