Comment 7 for bug 1847484

Hello. The crash that I experienced was very similar if not identical to this report. In my case, I was able to isolate the problem thus:

1. Start a tmux server in the background and issue a `tmux send-keys -t` at it – the server crashes.
2. Start a tmux server in the background, attach to the session, hit [q] in the frame that shows all of the errors in the old configuration, which was not updated since the upgrade to Eoan, and issue the same `tmux send-keys -t` again – now the server does not crash.

So, the crash seems to happen when sending keystrokes to a frame that is still showing error messages from parsing the configuration.
