I was playing around with trying to persuade XEmacs to forget about an
existing colour specification, when I got a core dump.
It appears to derive from an assert() in specifier_remove_locale_type,
specifier.c, line 1490.
assert() seems to be a rather drastic way of checking arguments which
are passed from Lisp.
