Too easy to accidentally quit unity

Binary package hint: unity

Not sure if this counts as a duplicate of bug 693777, but check the screenshot for what I mean. If nothing's focused, as happens under a few circumstances (for instance, right now, I can get to a no focus condition by dragging windows around, with wobbly enabled, so that the launcher hides; or, indeed, minimising a fullscreen window), then I can click on the menu area on the unity panel, and click "close" on the File menu that appears. At which point unity disappears (as you'd expect...).
