Also experiencing this. I've worked around all the mods in my game, but I can't bring myself to trying removing all of them; and I can't re-install Skyrim... I've gone too far in this game to attempt a fresh start. I suspect that custom races might be the issue revolving around this.. But I can't say that for sure. We really need someone to fix this, it's become unbearable. Let's hope a fellow Dovah will come to the homeless heroes' aid.
