apport doesn't work to run a gdb session when run with another terminal

Workaround was to set again defaut terminal as gnome-terminal using: "sudo update-alternatives --config x-terminal-emulator"
This could be a bug from terminator as I didn't dig yet into how a apport run the gdb command and what difference it make compared to running it within gnome-terminal.

This is the logic:

    def ui_run_terminal(self, command):
        terminals = ['x-terminal-emulator', 'gnome-terminal', 'terminator',
                     'xfce4-terminal', 'xterm']

        program = None
        for t in terminals:
            program = GLib.find_program_in_path(t)
            if program:
                break

        if not command:
            # test mode
            return have_display and program is not None

        subprocess.call([program, '-e', command])

I. e. does this somehow not work any more? terminator -x 'sleep 5'

terminator -x 'sleep 5' open up a terminator windows displaying error message "unable to find a shell"

Could be because my defaut shell is zsh instead of bash ? It works correctly if I run

- "terminator -x /bin/bash"
- "terminator -x "/bin/zsh"
- "terminator -e 'sleep 5'
