M-x image-mode RET 3. Insert the following text and press C-c C-c In Emacs 27.2 the outline of a rectangle is displayed as an image. In Emacs 28.0.91 an error is emitted at step 2: Debugger entered--Lisp error: (wrong-type-argument stringp nil) image-mode() funcall-interactively(image-mode) command-execute(image-mode record) execute-extended-command(nil "image-mode" "image-mod") funcall-interactively(execute-extended-command nil "image-mode" "image-mod") command-execute(execute-extended-command) Furthermore, inserting the text and pressing C-c C-c will do nothing because the error interrupts the mode activation. (A subsequent M-x image-mode RET after pasting in the snippet works.) Ergo, it is not possible to create an empty buffer in image-mode, as was possible in Emacs 27.2 and before.
