Tear in radial gradient background

I'm trying to cover the entire body of my website in a radial background, but I开发者_JAVA百科'm getting 'tears' (from lack of a better name). Seeing is believing, as they say, so rather than describing it further, go here to see it in all its glory: www.jorum.se.

I'll add an image for reference in case someone else has the same problem in the future.

html body {
    height:100%;
}

Simple as that!
