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.
