I am seeing an obscure problem with sgml-lexical-context  and Debian
emacs-snapshot, when used together with psgml as preferred sgml mode.
psgml provides 'sgml-mode, but has no `sgml-lexical-context'
definition. Either if I manually load 'sgml-mode' or trust autoload at
some points I get errors like.

Error in post-command-hook: (wrong-type-argument stringp nil)
sgml-lexical-context: Wrong type argument: stringp, nil

Function seems loaded since describe-function sgml-lexical-context
works, and I can even explicitly evaluate it in the buffer (and seems
to evaluate correctly).

Cheers,
