Don't hook to the combo itself. Use combo.entry, which gets you the
entry member of the GtkComboB. If you use entry.get_text() you'll
probably have no problems of this sort. If you do, try using
gtk.idle_add() on a function that gets the character buffer.

Yes, because you may notice that you are not declaring self as the first
parameter in your callback. But this may be something to do with
signal_autoconnect; I haven't used it in years.

Enter should not be required; it's bad usability. You should hook to the
following signals of the Combo's entry:
- insert_text
- delete_text
Take care,
