[rdiff-backup-users] Error on FreeBSD: "select: Bad file descriptor"

[Yann Golanski]

I am backing up two FreeBSD servers onto one.  One of those backed up
servers is on the other side of a firewall but apart from that they are
the same -- 5.2.1, python and rdiff-backup version match.  The one
inside the firewall works like a charm.  The one outside on the other
hand gives me the following error with the same command. 

Does anyone have an idea why this is so?

# /usr/local/bin/rdiff-backup --verbosity 6 address@hidden::/etc \
  /usr/vault/backups/raven/etc
