When attempting to use the standard camera app on my Nexus, I get this error. I've had a Nexus 5 since launch and had NO issues whatsoever with the camera until recently. No matter what I try to do, the camera app doesn't load. Not from the lockscreen, not from the app, etc.
What's odd is that I CAN use apps like camera zoom fx or the built in snapshot feature in the facebook app for example, and the camera works then. I can also use hangouts and I've verified the front facing camera works. Oddly though, using the camera within the Google+ app crashes the camera too.
I've tried clearing cache, dalvik cache, force stop camera, disabling and re-enabling and no dice. A friend of mine postulated that it could be the HDR mode messing up. I DID have HDR active the last time the camera worked. But with no way of resetting the application/toggling the HDR switch (because the camera won't load to that point), I'm SOL.
Here is a screen cap video I took demonstrating the issue. Don't mind the artifacting at the start of the video, I'm not sure what caused that.
My current phone build is in my sig, except I'm running the most up to date Franco Kernel (iirc r37).
