I reported a bug with similar symptoms a few hours ago.

For me it comes from an Org file that has a heading with no title but
just a bullet.

Here is a simple recipe:

1. emacs -Q
2. M-x which-function-mode
3. C-x C-f debug.org (file attached, outline with no heading)

See the following error 

   which-func-ff-hook error: (wrong-type-argument stringp nil)

For this recipe, it was a bug in `org-imenu-get-tree',
now fixed.  Thanks for reporting it!
