running tarsnapper --target "\$date-03-HOURLY-tripoli-/home/backups/media/Pictures" --deltas 1d 7d 30d 360d 18000d - expire --dry-run I get the following error:

I'm using Python 2.7.6.

It seems that the recently added Python 3 support is a bit broken; you can use an older version.

If someone could contribute fixes in this regard, I would appreciate it.
