Comment 6 for bug 1622386

To be honest I assumed the command line bug reporter would capture enough detail to identify the cause.

I've had it happen three or four times, but I can't get it to reproduce while my screen recorder is running. I've read everything I need to from that file, so I'm happy for you to close this bug report. Unfortunately I can't see an appropriate status for that - so feel free to close this report however you think best.
