*nods* That's why I don't even know where to begin on making a simpler
test case.

Previously, I was using a remote source with a local destination, but
that was causing me problems with NAT's and mobility and scheduling
and such.  As soon as I tried to switch to using a "remote"
(localhost) source with a remote destination, I encountered this
KeyError problem.

I'm happy to help.  I have a fair amount of experience debugging
Python, but no knowledge of the rdiff-backup source, so if you have
hints on where or how to start debugging it, I can dig into the code.

Nope.  All of the rdiff-backup-related files I have came from the
latest Debian package.  I also reinstalled the package on both sides
to rebuild the .pyc's, but to no avail.
