Actually thinking through the flow, it is currently my background thread that is calling the reload. I have commented that out and it is still crashing, but it is probably a thread safety issue. I will re-structure so that the background thread signals the main thread its work is done rather than call back into it, which is what it was doing. Will see how that goes...
