If there's an error which, for some reason, only happens when running emacsclient, then life becomes very difficult. I just encountered this with one of my users - I still have no idea why the error only affected emacsclient, or how I could have reproduced it without emacsclient, I eventually fixed it by bisecting their .emacs. Toy example: 1. emacs -Q 2. (server-start) 3. (add-hook 'before-make-frame-hook (lambda () (error "frame hook error"))) 4. emacsclient -c The output of emacsclient is: Waiting for Emacs... *ERROR*: frame hook error That's all, there is no way to get more information about the error that happened. Ideally, when emacsclient encounters an error and debug-on-error is non-nil, it should cause Emacs to enter the debugger.
