ERROR: failed to dump stream. Broken pipe

Hi,

I'm trying to set up a 2nd host that needs to copy all data on a btrfs volume from a 1st host. Installation went fine, but when running I get the following error:

root@host02-sync:/mnt/urbackup-btrfs# buttersink -n -d ssh://host02/mnt/urbackup-btrfs/ /mnt/urbackup-btrfs/
  Remote version: {u'btrfs': u'Btrfs v3.17', u'buttersink': u'0.6.8', u'linux': u'Linux-3.16.0-4-amd64-x86_64-with-debian-8.7'}

S|btrfs send errors

Just listing the snapshots does seem to work:

Hi,

Never mind. I've been searching on the wrong error :-) Searching on "ord() expected string of length 1, but int found" I found the solution.

For further reference, the following fixed it on debian jessie

vi /etc/apt/sources.list
deb http://ftp.nl.debian.org/debian jessie-backports main
apt-get update
apt-get -t jessie-backports install python-crcmod
pip uninstall crcmod
