It's actually common. If you use the Magic Trackpad gesture to invoke mission control, it's quite easy to accidentally depress the trackpad button while performing the gesture. This causes the app's event loop to get wedged, and you have to pump it manually with clicks in order to get it unstuck. (I've filed a radar.)
