>Description:
When tmux receives a key sequence "\033\0P" from shell, 
tmux server of the shell's pane stops responding any more.
Only the pane which received the key sequence is affected,
and other panes work fine.

>How-To-Repeat:
$ tmux -V
tmux 1.9a
$ ls .tmux.conf
ls: .tmux.conf: No such file or directory
$ type tmux
tmux is /usr/bin/tmux
$ echo $TERM
xterm
$ tmux

TMUX$ printf "\033\0P"
