Yeah, sorry, not the clearest statement ever.

Hmmm. Okay, well if I know that it *should* work, I can spend more time
trying to get it to do so.

No, this isn't the case. I'm running directly from internal IDE hard
drive. The /mnt/sdb1 part of the canonical name is a historical
accident, as the machine has two internal hard drives. I get the same
behaviour on other machines, with a single hard drive.
My apologies, anyway, I should have given a better bug report in the
first place. So, I have just tried to replicate this behaviour, with the
following steps. It's actually a multi-backend problem, it appears. So
emacs -Q
In *scratch* eval...
(add-to-list 'load-path "~/emacs/packages/dvc/lisp")
(require 'dvc-autoloads)
success.
Navigate to ~/emacs/packages/dvc/lisp. Add a blank line to a one of the
lisp files.
C-xVs (dvc-status) produces....

Place the cursor over "lisp/baz-dvc.el" (this is why you need to add a
blank line).

This is running a 10.04 Ubuntu (although it also occurs with later
Ubuntu's).
