Thanks for the detailed explanation.
The tmux server crashes with a [lost server] message as soon as I send a
mouse cursor escape sequence IF terminal-overrides option is defined in
.tmux.conf--no matter what I add, remove, or set.
For example, in .tmux.conf, I'll add this basic line: set -g
terminal-overrides "88col*:colors=88,*256col*:colors=256,xterm*:XT"
$ tmux -vvv new-session
$ echo -ne "\e[3 q"
[lost server]
At this point, my terminal is hosed, and I have to close it and start a new
one.
tmux-server and tmux-client logs: https://gist.github.com/saamalik/5692227
The tail lines from tmux-server.log is when tmux is dispatching the csi
cursor command.
input_parse: 'ESC' ground
input_parse: '[' esc_enter
input_parse: '3' csi_enter
input_parse: ' ' csi_parameter
input_parse: 'q' csi_intermediate
input_csi_dispatch: 'q' " " "3"
Also, I was poking around looking for more logs, and I found an entry in
/var/log/kern.log every time tmux crashed because of the mouse cursor
sequence:

What other information would you like? I'm using tmux 1.8 from installed
binary but I'm able to reproduce this on the latest master branch (git pull
/ configure / make / ./tmux )
