Sure.  It happens every time I run duplicity on the machine for an
incremental backup.  I've even tried deleting the full backup and
starting over.

If I wanted to go about debugging this, do you have any suggestions
for the best way to start?  By default I was going to just start with
some annotations to the code around the failure point.

Current run output is:
