I am also having the intermittent camera issue. Using the LED Light widget fixes it for me as well (thanks, OP!).
I have a feeling that the official 8/3 release will be the same as this one. I think they are just trying to get people to download it via the normal means next week. It seems insane to me that there would be this many bugs after it taking so long for them to release it. Ah well... I'm sure the devs will have these all fixed up in a new rom within a week.
