Bug Description

This appears to affect only Xubuntu 12.04 LTS, because other two Ubuntu 12.04 LTS systems I have (all packages latest) do not show this symptom.

When screen is started in a detached mode (screen -d -m) and later attached (screen -r), the stty settings get mangled, making any terminal window inside the screen session unusable. For instance, pressing a backspace erases the entire command-line.

Steps to reproduce:

$ sudo apt-get update
$ sudo apt-get upgrade
$ stty
speed 38400 baud; line = 0;
-brkint -imaxbel iutf8
$ screen -d -m
$ screen -r

(being attached to the screen session)

$ stty
speed 9600 baud; line = 0;
kill = ^H;
-imaxbel
tab3
$

If we start screen normally, everything is fine.
