Submitting a patch soon.
Without fix:
$ set|fgrep PS1|head -1
PS1='\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
With quotation fix applied:
$ set|fgrep PS1|head -1
PS1='\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' |

Expected:
debian_chroot part of xterm title should update dynamically; with the following PS1 contents by default
$ set | fgrep PS1 | head -1
PS1='\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
Actual result without patch:
debian_chroot part of xterm title got evaluated only during bash startup, as can be seen in PS1 contents
$ set | fgrep PS1 | head -1
PS1='\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' |
