Stealing your code, I get
Wrong type argument: stringp, #<buffer alternative_cluster_software.org>
as soon as I call my-buffer-file-newer-than-file-p
However, if I run it with "emacs -q" it works. So something in my
.emacs must be screwing things up. I thought maybe using uniqify was
the problem, but toggling it didn't make any difference.
Any ideas what the problem might be?
