In a normal python program, Ctrl-C will set up a KeyboardInterrupt and terminate the program. This works with a normal python script, including GTK2 gtk.main(), but GTK3 Gtk.main() (even when used in a more robust GTK program that coded below) will not terminate with Ctrl-C requiring a Ctrl-Z and killing the job to terminate. See the commmand line output below:

$ python -c "while True:
>  pass
> "
^CTraceback (most recent call last):
  File "<string>", line 1, in <module>
KeyboardInterrupt


$ python -c "import gtk
> gtk.main()
> "
^CTraceback (most recent call last):
  File "<string>", line 2, in <module>
KeyboardInterrupt

$ python -c "from gi.repository import Gtk
> Gtk.main()
> "
^C
^C
^Z
[1]+  Stopped                 python -c "from gi.repository import Gtk
Gtk.main()
"
$ kill %1

[1]+ Stopped python -c "from gi.repository import Gtk
Gtk.main()
"

The behaviour under Gtk.main() should be changed to respond to the KeyboardInterrupt.

The behaviour under Gtk.main() should be changed to respond to the
KeyboardInterrupt.

Well, you should report that to (Py)GTK folks then :-)
Either they set up a SIGINT handler, or they catch the KeyboardInterrupt exception, but that's not a problem with Python.
Closing.

Understood. I didn't realize it was 3rd party.
