Comment 11 for bug 882699

So, the error is the following (sorry, private, here for the developers): https://pastebin.canonical.com/55249/

It's essentially a locking problem on the database, which points to 2 write operations happening very close together.
Michael, is it possible deja dup is doing parallel operations?

If not, is there a way to reproduce this problem consistently? If there is, we can spend some time debugging on our end what's causing the lock-up.
