(backtrace)) Then launch M-x tmm-menubar to have it output the backtrace. When I test it on Emacs 23.4, I have a nice backtrace output, with one readable line per stack item. On r114884 this looks really ugly, unreadable. Some bytecode lines are mixed with words. The stack trace looks as though the compiled-function lisp type is printed, so I suspect that specbinding.bt.function changed its type, which also affects Vsignaling_function argument to command-error-function. I propose documenting the Lisp type of this structure member.
