Crash when using QRemoteObjectDynamicReplica in QML

Using any remote QObject as a dynamic replica in QML causes a crash.

Server:

QRemoteObjectHost host(QUrl(QStringLiteral("local:replica")));
QObject obj;
host.enableRemoting(&obj, "Test");

Client
 

QRemoteObjectNode node;
bool connected = node.connectToNode(QUrl(QStringLiteral("local:replica")));
if (connected) {
    auto replica = node.acquireDynamic("Test");
    connect(replica, &QRemoteObjectReplica::initialized, this, [replica, this] {
        engine->rootContext()->setContextProperty(QStringLiteral("replica"), replica);
    }
    replica->waitForSource(); // looks like this is needed to init the replica
}

Any access of "replica" in a QML file causes this crash.
