this may be a shot in the dark, but have you tried installing the python
modules for extended attributes and access control lists?
google searches for "Unable to import module xattr" and "Unable to
import module posix1e from pylibacl package" both turned up this thread:
http://lists.gnu.org/archive/html/rdiff-backup-users/2005-07/msg00023.html
may not be at all related, but it would be nice to rule out some simple
filesystem/os quirkiness.

I'm starting to wonder. I've had success with rdiff-backup on two other
servers, but this one is a pain in the !ss.
Could it be making a difference that I'm running a AMD 64bit cpu? I'm
also running two sata drives as raid1 with the built in software raid.
Could that mean anything?

I'm still relatively a newbie to linux even though I've been using it

"strace", and how would I be able to use to track down this segfault
problem?
strace follows a program and tracks down system calls etc. Its sometimes
useful, though generates a massive output for most things. If its
install simply doing 'strace command' will give you an idea.
Anyway, its probably not going to help you that much - its output is
pretty confusing.
can you try backing up to and from the same filesystem - ie try
rdiff-backup -v7 /home /tmp/home-backup
