Hi all, I recently came across this weird issue using org-mode. Essentially when I fold/unfold/fold some header in org-mode, pressing tab three times, I expect the section to fold again at the third keypress, and instead emacs freezes. By detective work I discovered that it has to do with having the '%p' option in frame-title-format. The bug disappeared when I took "%p" option away from frame-title-format.
Thank you for all you work and for any attention you will give to this bug. I hope this message is useful. I will now give enough info and data to reproduce the bug with a minimal setup, and at the end of the message my emacs/org/Linux configuration follows. * Steps to reproduce the bug Note that these steps only reproduce the bug when emacs runs graphically. Using "emacs -nw" fails to reproduce the bug. ** Step 0. Prepare a folder ~/bugreport/ with the three files "test.sh", "test.el" and "test.org" as follows ---- test.sh ---- downloads org-mode and runs emacs with the test setup cd ~/bugreport/ git clone https://code.orgmode.org/bzg/org-mode.git cd org-mode/ make autoloads cd ~/bugreport/ emacs -Q -l test.el test.org & ----------------------------------------- --- test.el ---- loads org-mode from the repository and set frame-title-format (add-to-list 'load-path "~/bugreport/org-mode/lisp") (setq frame-title-format '("%p")) ----------------------------------------- ---- test.org ---- just an org file with a header * Try to hang emacs To hang emacs you should fold/unfold/fold the header of this section a couple of times. ----------------------------------------- ** Step 1. Run the test It is sufficient to go "cd ~/bugreport/" and do "sh ./test.sh" You should see emacs starting and opening "test.org" file, and by running 'org-version' you could double check that the appropriate version of org has been loaded. ** Step 2. Make emacs freeze Go to first line in the "test.org" file and press TAB three times. Emacs should freeze now. * Emacs/Org/Linux configuration Here's some more details about my environment.
