Here is the recipe: 1. emacs -nw -Q -l ~/minimal-org.el ;;; minimal-org.el: Minimal setup to load latest `org-mode' ;;; Code: (setq debug-on-error t debug-on-signal nil debug-on-quit nil) (add-to-list 'load-path (expand-file-name "~/build/org-mode/lisp")) (require 'ox-beamer) (add-to-list 'org-latex-classes '("beamer" "\\documentclass\[presentation\]\{beamer\}" ("\\section\{%s\}" . "\\section*\{%s\}") ("\\subsection\{%s\}" . "\\subsection*\{%s\}") ("\\subsubsection\{%s\}" . "\\subsubsection*\{%s\}"))) 2. C-x C-f some-file.org RET 3. Now try to export: C-c C-e. You can see menu options for beamer export. 4. Now reload Org: C-c C-x !. Try step 3 again. You will notice the entries for beamer is missing. This might actually be a problem with ox-beamer and not org-reload because I noticed my other Org customisations do stay intact (which is of course in line with your comment about settings not being touched). Instead of step (3), you could also try M-x org-beamer-export-as-latex. After step (4), repeating this alternate step (3) should give you the following backtrace. Debugger entered--Lisp error: (error "Unknown \"beamer\" back-end: Aborting export") signal(error ("Unknown \"beamer\" back-end: Aborting export")) error("Unknown \"%s\" back-end: Aborting export" beamer) org-export-barf-if-invalid-backend(beamer) org-export-as(beamer nil nil nil nil) org-export-to-buffer(beamer "*Org BEAMER Export*" nil nil nil nil) org-beamer-export-as-latex() call-interactively(org-beamer-export-as-latex record nil) command-execute(org-beamer-export-as-latex record) execute-extended-command(nil "org-beamer-export-as-latex") call-interactively(execute-extended-command nil nil) command-execute(execute-extended-command) Hopefully my recipe is complete to fix this issue.
