[rdiff-backup-users] v0.12.3: Security violation on robust.install_signal_handlers

[Randall Nortman]

I'm running rdiff-backup remotely via ssh, using --restrict-read-only
for security. The command being run on the remote (source) side is a
shell script containing only the following command:

/usr/bin/python2.2 /usr/local/bin/rdiff-backup --server --restrict-read-only 
/etc

The command executed on the local (target) side is:

rdiff-backup --remote-schema 'ssh -C %s /path/to/script' hostname::/etc 
/path/to/target


When I try to run a backup, I get this:

Traceback (most recent call last):
  File "/usr/local/bin/rdiff-backup", line 24, in ?
    rdiff_backup.Main.Main(sys.argv[1:])

I was using exactly the same setup (same arguments, etc.) with version
0.10.1 without a problem. (I upgraded because I want to preserve
uid/gid even though the backup user is not root.)

Am I doing something wrong, or is this a bug?

Thanks for any help,
