x-popup-dialog with Mac event -> wrong-type-argument

[David Reitter]

The Carbon port calls x-popup-dialog with a core-event it cannot  
process. This occurs when a buffer is in modified state and the user  
chooses "Quit Emacs" from the application menu (rather than doing C-x  
C-c which would not cause a GUI dialog to be shown).

Wrong type argument: listp, [core-event quit-application]

Thanks for the report.  I've just installed a fix.
