Title in Terminator becomes "/bin/bash"

[madurangasiriwardena]

Title of the Terminator in Ubuntu becomes "/bin/bash" after changing PS1 to "${debian_chroot:+($debian_chroot)}\u@\h:\w [$txtcyn]$git_branch[$txtred]$git_dirty[$txtrst]$ "

But adding "[\e]0;\u@\h: \w\a]${debian_chroot:+($debian_chroot)}\u@\h:\w [$txtcyn]$git_branch[$txtred]$git_dirty[$txtrst]$ " as the PS1 variable resolves the issue. I have modified the default PS1 variable with the value provided in readme.
