Default [Q] Viperone ROM Camera bug

Hi guys, I'm a new member so can't yet post in the official Viperone ROM thread in the developers forum so this seems the best alternative.

I have a repeatable issue running the latest version of the ViperOne ROM (version 4.3.0, build 4.06.1540.3 with kernel version 3.4.10). When I use the camera, if I leave the camera app running and lock the screen via the power button the phone will not come out of sleep and requires a hard reset (Power+Vol up) to restart. Any advice on fixing this would be great as I am a photographer and use the HTC One all the time to grab test shots and ideas for future shots.
