Subject: 24.0.50; x-popup-dialog can freeze Emacs on OS X
Date: Mon, 25 Jul 2011 16:37:58 +0200

From emacs -Q evaluating:

(x-popup-dialog t "hi")

will bring up a dialog with no way to dismiss it and no way to close it.  I have to force quit Emacs.  I can only test it on OS X right now.

I realize this is not the proper way to invoke x-popup-dialog, but something similar seems to be the cause of a problem that just happened to me in Customize.  I cannot reproduce it now, but ns_popup_dialog was in the gdb backtrace (which I foolishly didn't save), so I tried just running x-popup-dialog before reading the docstring and ran across this.  In the problem that I saw from inside customize I did not see a dialog at all, but the other symptoms were the same, so it may be that the dialog was displayed off screen where I simply couldn't dismiss it.



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

Hello.

I checked in a fix so x-popup-dialog behaves the same as the X11 versions of 
Emacs, i.e.: (x-popup-dialog t "hi") throws an error, and if no buttons have 
been specified, as in (x-popup-dialog t '("hi")), an "Ok" button is shown.

	Jan D.
