I'm not sure we can allow entering the debugger from server-execute. That function is documented as being called from timers and process filters, so entering the debugger might be unsafe. Stefan, any comments?

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.
