Photo Booth freezes for >30s whenever I open it

I've had this problem ever since I upgraded from Mavericks. Whenever I open Photo Booth, the application seems to be stuck on startup and I have to wait for like 50 seconds for it to become useable. A few months ago, it used to be like 20 seconds but it seems like the waiting time gets higher all the time.

Im using a Macbook Pro Retina 15 inch Early 2013.
