Lost VM backups becuause of this bug.  Also affects zsnapd package.
Upstream
1.5.7 fixes this bug, and backups work...

Python 13 syslog.syslog() throws ValueError exceptions when the log messages
usually created by this package are sent.  This broke the secure ssh
transfer
set up via zsnapd-rcmd sshd received command regexp filtering on the backup
target, which uses root ssh access.  Fortuneately if failed securely, but I
lost a lot of work as ZFS backups were not functioning.

We believe that the bug you reported is fixed in the latest version of
python-magcode-core, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
