Are you using a camcorder app for the short cut? If so which one and have you tried a different camcorder app? Does it crash if you don't use the short cut, by using it from the app's drawer?
I've never thought about having a camcorder short cut on the home screen but it is a good idea to have it for quick video recordings. Since I've read this thread, I found Shoot on Google Play and installed it. It's working out pretty good for now.
Just a thought!
