On the current master, I noticed this error when completing for some
function names, such as ``C-h f package-'':

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  string-match("\\(\\`\\|/\\)package-x\\(\\.elc\\|\\.el\\|\\.so\\)?\\(\\.gz\\)?\\'" nil nil)
  help--loaded-p("package-x")
  help--load-prefixes((("package-" "package-x" "package")))
  help--symbol-completion-table("package-" #[257 "\300!\206	\211\301N\207" [fboundp function-documentation] 3 "\n\n(fn F)"] lambda)
  test-completion("package-" help--symbol-completion-table #[257 "\300!\206	\211\301N\207" [fboundp function-documentation] 3 "\n\n(fn F)"])
  completion--do-completion(20 27)

It seems that I have a bare (nil) in the load-history, which
help--loaded-p doesn't like.

Is this expected?
This doesn't occur on emacs 25.1

Which commit are you on?

I am on the b2b3159 build "mm-decode.el: Simplify regexp used to search
html meta tag" .. cannot recreate this problem in emacs -Q or with my
config loaded:

I'm on 589bd0c22b2d55c3d0339221f67235b33be93f68.

I cannot replicate this with -Q either, so there's something that is
triggered by my setup.

However, emacs25 (from debian unstable) on the same configuration does
not trigger the issue.

Seems `help--loaded-p' does not handle an (nil ...) entry correctly in
the `dolist'.  Looks like an obvious bug to me.


Michael.

Are bug reports out of fashion?

To reproduce in "emacs -Q":

(defun test () "" nil) ;; insert text in buffer *scratch*
C-M-x ;; eval-defun (adds an entry to load-history with null file)
C-h f package- TAB ;; crashes
