Right, so you're getting back an error message, which means that we hit
the "else" bit here.

    (if (eq (xml-node-name (car tree)) 'DAV:multistatus)
        (url-dav-dispatch-node (car tree))
      (url-debug 'dav "Got back singleton response for URL(%S)" url)
      (let ((properties (url-dav-dispatch-node (car tree))))
        ;; We need to make sure we have a DAV:status node in there for
        ;; higher-level code;
        (setq properties (plist-put properties 'DAV:status overall-status))
        ;; Make this look like a DAV:multistatus parse tree so that
        ;; nobody but us needs to know the difference.
        (list (cons url properties))))))

And

(url-dav-dispatch-node (car tree))
=> " "

which means that the plist-put fails, of course.

But I'm totally unfamiliar with url-dav (and DAV), so I have no idea
what it really should be doing here.  It says that it tries to return a
DAV:multistatus parse tree...  but what do those look like (when you
don't have an error)?
