Subj : JS_NEWCONTEXT crashing

Hi, I've been trying to get XPConnect working in my application but I'm
having problems getting the Javascript environment setup. I'm basically
trying to use the code from the xpcshell sample.

However when I call JS_NewContext it crashes at JS_LOCK_GC(rt);
(rt->gcLock is NULL), however this works inside the xpcshell
application.

if I compile without the JS_THREADSAFE define it insteads asserts here:
 if (rt->state == JSRTS_DOWN) {
            JS_ASSERT(first);
            rt->state = JSRTS_LAUNCHING;
            break;
        }

Anyway here is my code, any help is appreciated.

Thanks,

 nsCOMPtr<nsIServiceManager> servMan;
        rv = NS_InitXPCOM2(getter_AddRefs(servMan), nsnull, nsnull);
        if (NS_FAILED(rv)) {
            printf("NS_InitXPCOM failed!\n");
            return 1;
        }
        {
            nsCOMPtr<nsIComponentRegistrar> registrar =
do_QueryInterface(servMan);
            NS_ASSERTION(registrar, "Null nsIComponentRegistrar");
            if (registrar)
                registrar->AutoRegister(nsnull);
        }

        nsCOMPtr<nsIJSRuntimeService> rtsvc =
do_GetService("@mozilla.org/js/xpc/RuntimeService;1");
        // get the JSRuntime from the runtime svc
        if (!rtsvc) {
            printf("failed to get nsJSRuntimeService!\n");
            return 1;
        }

        if (NS_FAILED(rtsvc->GetRuntime(&rt)) || !rt) {
            printf("failed to get JSRuntime from
nsJSRuntimeService!\n");
            return 1;
        }

        cx = JS_NewContext(rt, 8192);
