Thanks for the bug report. Unfortunately we don't have any other reports of this in Bugzilla, and if you can't reproduce it, then there's almost no chance we can debug it. I think this is a situation where we'll hope it shows up in our Sentry instance that aggregates automatic crash reports. So feel free to opt into automatic crash reports if you haven't done so already. Then we'll hope that the report on Sentry will become actionable if and when other people experience it as well so we can debug it with the more complete set of information there. Thanks anyway!
