Comment 4 for bug 23244

Here's the output you requested. I'm running breezy (final) now and control-k
still creates a new tab in gnome-terminal if I map control-t to create a new
tab. So most of the time I map shift-control-t to be create-tab - then I can
use control-k without it making new tabs (although then shift-control-k makes a
new tab, but I never type that).

Incidentally, here's the corresponding xev output for shift-control-k:

Note that I've not applied the 2 .deb patches in bug 21595, and was experiencing
keyboard problems related to that bug for some time.

This may be related.
