This looks like a problem in bash. gnome-terminal closes because the
bash process ends. I can reproduce it with the following commands:

mkdir -p "/tmp/data/unklllllllll/llllllllllllllllll/ΠΠ-07-Ααααααα βββ γγγγγδδδδδ δδδδδδδδδδδδ/εεεεεεεε/θθθθ-άάά 2-θθθθθό ώωωωω ύυυυυυαααααααααββββ/Plot-LLC (3350)/"
cd "/tmp/data/unklllllllll/llllllllllllllllll/ΠΠ-07-Ααααααα βββ γγγγγδδδδδ δδδδδδδδδδδδ/εεεεεεεε/θθθθ-άάά 2-θθθθθό ώωωωω ύυυυυυαααααααααββββ/Plot-LLC (3350)/"

To crash, it requires the terminal width to be narrow, under 80 columns
or so, and a fancy prompt. I'm using the colored prompt from the default
.bashrc:

PS1="\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ "

Backtrace is attached.
