Anyone having camera issues, use this .apk file instead:
Vanir Camera2.apk
I extracted this from the 2/3/2014 build of Vanir ROM and then swapped out the one that came with Carbon ROM, in the zip file itself. Just drag and drop in the location system/app, choose "yes" to replace the existing camera2.apk file. Did a clean install of the latest Carbon nightly to test, had no freezes or crashes when switching every possible combo I could think of-front camera, rear camera, video. Took multiple pics and shot several seconds of video every time I switched, no problems. Hope this helps!
