Comment 9 for bug 753610

I am getting the same behavior in emacs 24.0.90.15.

I get this message when I open certain php files.

Debugger entered--Lisp error: (error "fun-var-sym=mumamo-eval-in-html-mode, use-major-entry=(html-mode (mumamo-eval-in-html-mode mumamo-def-eval-in-html-mode mumamo-kw-eval-in-html-mode))")
