If you want to live on the bleeding edge, it’s easy enough to get a non existing release of GNU Emacs under debian sid, thanks to http://emacs.orebokech.com/.

The problem is that Emacs Muse is broken on emacs-snapshot, partly because of Htmlize which is unable to find the face fonts (I got (error "Invalid face")), partly because of my configuration itself:

hunk ./dim-muse.el 22
-      '(("pgsql.tapoueh.org" $
-        (,@(muse-project-alist-dirs "~/dev/muse/site") $
+      '(("pgsql.tapoueh.org" ("~/dev/muse/site"
+        ;;(,@(muse-project-alist-dirs "~/dev/muse/site") $

The solution was to switch to using Emacs 22 on sid for pgsql.tapoueh.org editing, while using EmacsCVS for other activities.

And I’m using the patched Htmlize on both the versions, by the way.
