Thank you. The problem I reported was fixed in 0.12.16, but it seems
there are still problems on Quit command.
If I selected "New window" or "New tab" before Quit command, lttv
sometimes crashes or freezes. Though I cannot find a reliable way to
reproduce it, here are some examples:
1. New tab, Quit, then crash
