Default Google now bug

Every time I long press the home button and it opens the google now it crashes, it simply does nothing until I turn off the screen and on again, after turning on the screen again it works normal but it happens every time and it's becoming annoying. Does this happen to someone else but me?

Here is a video http://youtu.be/PqT-V1RWLcE
