I've recently noticed that when I quit my app with Command-Q, it will crash:

This is a full-screen "kiosk" type of app that hides the menu bar and Dock (uses SetSystemUIMode). On the main "screen", I have a Quit button. When I use that to quit, no crash occurs.
The menu bar that is hidden does have a Quit item with the Command-Q equivalent. From the crash report, I can see that the menu is ultimately sending the terminate: action.
But that's what the action method of my quit button does (it simply does [NSApp terminate:self]).
Has anyone else experienced this problem? Is this something to do with the menu bar being hidden?
Something I've thought about as a workaround is to remove the Quit menu item from the menu bar (or at least the key equivalent) and process Command-Q manually. After all, users will never interact directly with the menu bar; it's simply never shown.
Thanks for any tips you may have.
