WebKit is not thread-safe, and a lot of WebKit classes will even throw exceptions if you try creating or accessing them in background threads. So what you observed doesn't surprise me too much... Of course, if you really want to know what's going on, then you can try downloading the WebKit source from <http://webkit.org/> and building your application against an open-source build of WebKit rather than the system's build.
