lazy-completion-table seems to be broken for bibtex-mode.
bibtex-reference-keys is initialized via lazy-completion-table.
Yet when I use minibuffer completion for bibtex-search-entry
(which is using bibtex-reference-keys for completion) it gives me
the error message

completion--some: Symbol's value as variable is void: lambda

The usage of lazy-completion-table by bibtex-mode did not change
since emacs 22 where minibuffer completion has been working fine.
Yet the internals of lazy-completion-tables have changed since then.
Is there anything bibtex-mode needs to do different now?

emacs -Q foo.bib
M-x bibtex-search-entry RET TAB
works fine for me.

Suggest maintainer-clean + bootstrap (unless you were talking about
something else).

The variables bibtex-reference-keys and bibtex-strings are
initialized by lazy-completion-table. And in several instances,
bibtex-mode was using nlistp to test whether these variables have
their initial values. That was working fine at some point but not
anymore.  lazy-completion-table was already fixed quite some time
ago by Stefan in order not to use listp internally for such a test.
Now I've updated bibtex-mode too, so that it uses functionp.
