it worked for me too for a few hours....then it crashed the springboard
see what you mean - when I try to launch the clock it does not crash springboard - but the clock app does not open either!
no biggie for me though as I never use the native clock app. I'm happy with the live icon, plus I expect it will get updated via cydia sometime.
edit: clock does of course launch via spotlight, which is my prefered method of launching
