But now I have a "Your tab just crashed" core dump, and it looks
like this:

The are around line 136 of js/xpconnect/src/nsXPConnect.cpp is:


// static
void
nsXPConnect::InitStatics()
{
    gSelf = new nsXPConnect();
    gOnceAliveNowDead = false;

    // Initial extra ref to keep the singleton alive
    // balanced by explicit call to ReleaseXPConnectSingleton()
    NS_ADDREF(gSelf);

    // Fire up the SSM.
    nsScriptSecurityManager::InitStatics();
    gScriptSecurityManager = nsScriptSecurityManager::GetScriptSecurityManager();
    gScriptSecurityManager->GetSystemPrincipal(&gSystemPrincipal);
    MOZ_RELEASE_ASSERT(gSystemPrincipal);

    JSContext* cx = XPCJSContext::Get()->Context();
    if (!JS::InitSelfHostedCode(cx))
        MOZ_CRASH("InitSelfHostedCode failed");
    if (!gSelf->mRuntime->InitializeStrings(cx))
        MOZ_CRASH("InitializeStrings failed");

    // Initialize our singleton scopes.
    gSelf->mRuntime->InitSingletonScopes();
}

and line 136 is the first MOZ_CRASH() call.

Hints?
