emacs - Shell prompt repeating when using ssh in ansi-term -

when use ssh login ubuntu 12.04 machine ansi-term session in emacs prompt displays incorrectly:

0;ubuntu@jumplin: ~ubuntu@jumplin:~$ 

this should following:

ubuntu@jumplin:~$ 

i've tried few of suggestions in relation utf-8 , colour support don't seem working (colour works fine in ansi-term):

strange characters in ansi-term in emacs

i think might have unsupported ansi escape code or that, i'm not sure - value of ps1 terminal session is:

\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ 

any advice appreciated :) seem bit lost when strange characters show in terminal sessions.

\[\e]0;\u@\h: \w\a\] in prompt configure xterm(?)'s title bar. though ansi colorization supported ansi-term, escape sequences manipulate title bar not. why see prompt repeated twice - first section supposed go title bar.

so either remove first sequence ps1 or similar suggested in bash prompt howto:

function proml { case $term in     xterm*)         local titlebar='\[\033]0;\u@\h:\w\007\]'         ;;     *)         local titlebar=''         ;; esac  ps1="${titlebar}\ [\$(date +%h%m)]\ [\u@\h:\w]\ \$ " ps2='> ' ps4='+ ' } 

you can test if in ansi-term, term equal eterm-color.
