For some reason, a manually triggered backup from deja-dup worked this
time, and it did an incremental backup. I'm not sure what changed, as it
had failed multiple times today.

- When you upgraded to 0.7.15, did you remove the distro's version?

I use the distro's package (Fedora has 0.7.15)

- How much memory do you have? Is it the same as previous?

Yeah, I have 16 GB of RAM, so I doubt that's the problem.

- How long of an incremental change list do you have?

How do I get that?

- Have you tried making a full backup?

Making full backups works fine it seems, it's only incremental that's
broken.

Title:
  MemoryError while verifying backup

Status in duplicity package in Ubuntu:
  New

Bug description:
  While trying to verify a backup (launched from deja-dup), I receive
  the following error.  My system currently shows 11G of RAM available
  plus 23G of swap.  Possibly related to #1720159?
