Can't change gnome-terminal tab's title from within ssh session on debian 8 machine

Hi,

I'm having problems changing gnome-terminal tab's title when connected to machine running debian 8 over ssh. Right after starting ssh session it changes title to `USER@HOST: CWD` and I don't see a way to change it to whatever I want it to be. Some shell transcript:

$ ssh deb6-server

$ echo -en '\e]0;test\a'

# title changes

$ echo $TERM

xterm-256color

$ cat /etc/issue

Debian GNU/Linux 6.0 \n \l

$ exit

$ ssh deb8-server

# here the title changes to USER@HOST: CWD

$ echo -en '\e]0;test\a'

# title doesn't change

$ echo $PROMPT_COMMAND

$ echo -en '\e[0;34mtest\e[0m\n'

test # written in blue

$ echo $TERM

xterm-256color

$ cat /etc/issue

Debian GNU/Linux jessie/sid \n \l

Do you have any idea what it might be or what to check?

Just in case, here's corresponding unix.stackexchange.com question: http://unix.stackexchange.com/questions/176186/cant-change-gnome-terminal-tabs-title-from-within-ssh-session-on-remote-debian
