If I try and start w3 I get this failure: Signaling: (wrong-type-argument number-char-or-marker-p nil) +(nil 12) font-spatial-to-canonical("+12pt") css-expand-length("+12pt" t) css-expand-value(height "+12pt") css-parse-args(235 254) css-parse("file:/usr/gnu/lib/xemacs/packages/etc/w3/stylesheet" nil nil) w3-find-default-stylesheets() w3-refresh-stylesheets() w3-do-setup() #<compiled-function nil "...(68)" [w3-setup-done w3-do-setup w3-track-last-buffer bufferp w3-last-buffer buffer-name switch-to-buffer message "Reusing buffer.
