So why do you tie the crash to the progress indicator? I'm not saying you're
wrong, but you don't demonstrate that you're right, either. Is there
evidence for this? If you comment out the two lines starting with "spinner"
and try again, does the crash happen now? Does the backtrace on the "big
crash" indicate that the progress indicator is involved?
