i'm on Debian Wheezy x86_64 (+updates), running a manually 
compiled Emacs 24.4.1, and have not so far managed to reproduce 
this. However, i'm not sure what you mean by "Click once" and 
"Click again" - where are you clicking in each instance?

Menu → Options → Set Default Font → (Slide the font value up and then) SELECT (button)

That's what i guessed, and that's what i did - i don't get a 
segfault. However, i'm on Debian stable, not testing, so it might 
be an issue with one of the libraries used by testing to build 
Emacs; you might like to report it as a Debian bug:

https://www.debian.org/Bugs/Reporting

Existing bug reports for Emacs on testing can be found here:

-Q disables loading of .emacs/init.el and site-start.el.  -q disables
loading of .emacs/init.el but not site-start.el.  So, the problem is
probably in site-start.el which is a debian file.

I see no problem on Xubuntu.  You clarified that "click once" means
click on "Select".  What does "Click again" mean?  When I click on
select the pop-up window disappears and I see the Emacs frame with huge
text.  I can click on things in the frame with no problem.

Emacs crash

[Rusi]

Can someone check this recipe for crashing emacs please?

Ubuntu 16.4 running vanilla Unity -- yes this is likely related to X/WM stuff
emacs 24.5.1

1 Start emacs with
$ emacs --daemon

init contains just this 2 line function:

(defun kill-later ()
  (run-with-timer 1 nil 'save-buffers-kill-emacs))


2. 
$ emacsclient -n -c somefile
[somefile exists]

3. Write something there (ie dirty it and get a '*' in modeline)

4. Remove the frame by clicking the X in the frame

5. Try to kill emacs with
$ emacsclient -c  -e '(kill-later)'

6. top shows emacs running at 100% usage

7. killing it in top causes an apport crash

Note 1 Why is kill-later defined in that round-about way?
Because directly invoking save-buffers-kill-emacs from emacsclient
makes the -n option ignored
This in turn causes the save-buffers-kill-emacs to say "You have clients"

Note 2 If an emacs frame is present the save-buffer dialog appears as expected
and there is no issue
