 Sometimes my sandboxed-tor-browser (running Tor Browser 7.5.2) works ok.
 But sometimes it gets into a fit of "Gah. Your tab just crashed" failures.
 When those happen, I get this string of complaints in my stdout:

 Is this just #25540-come-early, or is this a little simple bug that should
 be found and squashed? :)
