Such a message in the "Warnings" window. "Frameset" I think refers to the .emacs.desktop file. I got this message when Emacs in daemon mode restored the desktop. There is no such message when running the GUI Emacs.

What could be wrong? How to debug it?

(defun herman/try-read-desktop ()
    (when (desktop-save-mode t)
          ; your init code here
          (message "Inside server-after-make-frame-hook")
          ;; (setq desktop-save-mode t)
          (desktop-read)
      ))

(add-hook 'server-after-make-frame-hook 'herman/try-read-desktop)

  • (setq toggle-debug-on-error t) first, and then add the backtrace to your question.

  • It looks like the error will be coming from (desktop-read) though, so you can also test just calling that directly.

    Apologies; that should be (setq debug-on-error t). I'd written M-x toggle-debug-on-error initially but realised you needed it set before you could interact with Emacs, and I messed up the edit.

  • You can also do M-x debug-on-entry desktop-read, if you want to go through it carefully.

I found the answer at https://stackoverflow.com/questions/18612742/emacs-desktop-save-mode-error#comment47963002_26546872

(setq desktop-restore-forces-onscreen nil)
