Subject: [ruby-talk:29737] ruby-mode and xemacs

Hi !

When I try ruby-mode with xemacs, the buffer is not fully fontified
(just comments and strings). If I activate the debug on signal, I get
this backtrace :

I use XEmacs 21.4.6 "Common Lisp" and I have run through the same
problem with XEmacs 21.4.4 "Artificial Intelligence". I have tried
ruby-mode revision 1.37 (the latest one) and ruby-mode from Ruby 1.6.5
with no changes. I have loaded font-lock prior to the ruby-mode with
no changes.
