Default [Q] Camera / GApps Freeze

I have the original xperia z running the latest 4.4 dirty unicorn ROM teamed with the pa GApps. I feel like I've tried everything but I keep finding that my camera will randomly freezes up and I have to force restart. I've tried other GApps, wiped and so on but it just keeps happening. Its so odd as its not a force close nor does it always happen, it also happens in apps that use my camera like Snapchat. Can someone shine some light?
