(Thorsten asked me to repost this from github.)

When calling navi-search-and-switch interactively, I get the following
backtrace:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  navi-rename-buffer()
  navi-search-and-switch()
  call-interactively(navi-search-and-switch record nil)
  command-execute(navi-search-and-switch record)

The problem seems to be with this code in navi-rename-buffer

#+begin_src emacs-lisp
(with-current-buffer
    (if (eq major-mode 'occur-mode) (current-buffer) (get-buffer "*Occur*"))
#+end_src


As there is no "*Occur*" buffer, and the current buffer is in
emacs-lisp-mode, =(if (eq major-mode 'occur-mode) (current-buffer)
(get-buffer "*Occur*"))= returns nil and with-current-buffer fails.

I think it is. Here is my current configuration:

#+begin_src emacs-lisp
(add-hook 'message-mode-hook 'outline-minor-mode)
(add-hook 'emacs-lisp-mode-hook 'outline-minor-mode)
(require 'outshine)
(add-hook 'outline-minor-mode-hook 'outshine-hook-function)
(require 'navi-mode)
#+end_src

and I see "Outl" in the list of minor modes.
