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

    (with-current-buffer
        (if (eq major-mode 'occur-mode) (current-buffer) (get-buffer "*Occur*"))

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.

Hi Thorsten,

Just curious, have you thought about getting language keywords from imenu instead of hardcoding your own lists? It seems like it could reduce the maintenance burden and also add support for more languages for free.

I know you're probably not interested in doing this yourself, I'm just asking to see what you think, if maybe you had already tried, etc. :)

Thanks.

Would you accept a patch that turns outorg into an optional dependency, e.g. by wrapping the definitions of navi-edit-as-org and navi-mail-subtree with (eval-after-load 'outorg ...)?
