Wrong type argument: stringp when Generating cus-load.el

[Andi Hechtbauer <anti@spin.de>]

Hi,

from time to time I do a clean compile of CVS gnus, as I usually just
"make some".  But this morning (and up til now, using the freshest CVS
gnus) the procedure "make distclean; ./configure; make" broke at
making gnus-load.el:

 $ make
 cd lisp && make EMACS="emacs" lispdir="/usr/share/emacs/site-lisp" all
 make[1]: Entering directory `/home/anti/lib/emacs/pgnus/lisp'
 rm -f *.elc gnus-load.el
 URLDIR=no W3DIR=no lispdir=/usr/share/emacs/site-lisp srcdir=. emacs -batch -q -no-site-file -l ./dgnushack.el -f dgnushack-make-cus-load .
 Loading cus-dep...
 Directory .
 Generating cus-load.el...
 Wrong type argument: stringp, (mm-inline-text-html-with-w3m-keymap custom-variable)
 make[1]: *** [gnus-load.el] Error 255
 make[1]: Leaving directory `/home/anti/lib/emacs/pgnus/lisp'
 make: *** [lick] Error 2

This is after I configured away url and w3, having them activated
makes no difference.

Is this obvious to one of you?  Has anyone seen the same thing and can
shed some light on a lisp-dummy?

Thanks for looking,

Andi
