Seg fault: WorkerScript.onMessage called after destructor

uroller

I've started seeing a segmentation fault after adding a WorkerScript to load my ListModel.

@
Rectangle
{
Component.onDestruction: console.log('onDestruction')

ListModel { id: listModel; }

WorkerScript {
    id: worker;
    source: "worker.js";
}

}

WorkerScript.onMessage = function(msg)
{
console.log('onMessage++')
if (msg.action == 'clear') {
msg.model.clear();
msg.model.sync();
}
console.log('onMessage--')
}
@

I can see WorkerScript.onMessage is being called after Component.onDestruction.

@
onDestruction
onMessage++
Segmentation fault (core dumped)
@

I presume this can happen if my WorkerScript is doing something time consuming when the destructor is called too.

I don't see any way for a WorkerScript to communicate back to the Component to say it's busy or a way for the Component to stop a WorkerScript.

I've tried Qt 4.8.4 and Qt 4.8.5.

Edit: Problem still exists in Qt 4.8.6.

Loader and WorkerScript don't work well together.
