I just tried backing up to and from the same filesystem with the the same result, below:

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
for almost two years, so excuse me for the ignorance.  What is
"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
