Description Carlos Garcia Campos 2012-08-20 06:24:28 PDT 
To reproduce:

 1.- load a page with WKPageLoadURL
 2.- load an invalid page and in load error callback load alternate page with WKPageLoadAlternateHTMLString
 3.- load another page with WKPageLoadURL
 4.- WKPageGoBack() -> alternate page is loaded
 5.- WKPageGoBack() -> alternate page is loaded again
.....

So it's not possible to go back from the alternate page. The problem is that FrameLoader::shouldReloadToHandleUnreachableURL() assumes loads happens synchronously, which is true in WebKit1 but not in WebKit2, and for WebKit2 compareDocumentLoader is always NULL and shouldReloadToHandleUnreachableURL() never returns true.
