edebugging this, the problem is here:

      (when (re-search-forward
             ;; bzr prints paths relative to the repository root.
             (concat "^\\(" vc-bzr-state-words "\\):[ \t\n]+"
                     (regexp-quote (vc-bzr-file-name-relative file))

where that function can return nil:

(defun vc-bzr-file-name-relative (filename)
  "Return file name FILENAME stripped of the initial Bzr repository path."
  (let* ((filename* (expand-file-name filename))
         (rootdir (vc-bzr-root filename*)))
    (when rootdir
         (file-relative-name filename* rootdir))))

And regexp-quote on nil doesn't work very well.

I don't know why this function is called at all, though.  Could it be
some local customisation I have that affects this?  I'll try with emacs -Q.
