I believe the change I'm going to make for https://bugs.webkit.org/show_bug.cgi?id=53716 will fix this as well.  Basically changing Source/WebCore/bridge/jsc/BridgeJSC.cpp

From:
 void Instance::willDestroyRuntimeObject(RuntimeObject* object)
 {
     ASSERT(m_rootObject);
    ASSERT(m_rootObject->isValid());
    m_rootObject->removeRuntimeObject(object);
     m_runtimeObject.clear(object);
 }

To: 
 void Instance::willDestroyRuntimeObject(RuntimeObject* object)
 {
     ASSERT(m_rootObject);
    if (m_rootObject->isValid())
        m_rootObject->removeRuntimeObject(object);
     m_runtimeObject.clear(object);
 }
