Looks like you need to tweak settings in your Advanced Lighting window. Increase the samplepoints, increase the filter size, or .. uh.. something else. Check the helpfile for descriptions of each parameter, and decide for yourself what you think needs tweaking. Do testrenders for each tweak, and at some point you should be able to figure out what is producing those artifacts.

Using GI solutions is always a tricky thing, and generally always results in having to tweak settings to get an acceptable speed/quality ratio going. There is no one setting that removes it.

I think the most likely ones would be amount of samples and filter size though. ..oh and the subdivision rollouts at the buttom of the that window, that you can set to 1x1. That way it will sample each pixel, instead of, at 16x16 for instance, sampling every.. well.. 16x16 pixels at a time. The tradeoff is speed of course, nothing comes for free.

Oh.. that.. seems like a strange setting to make it go away. Oh well. Check your environment window and enable one of the Exposure Control modes. That often helps when you're dealing with Advanced Lighting. Infact, if I'm not much mistaken, activating one is part of steps in using the Skylight.

You know I ended up having the same problem and ended up just recreating the model as it was taking too much time for me to figure out what the hell was wrong with it.
