That is almost certainly KDE bug #176902. Multiple tabs, check. 24
lines instead of 40, check.

At least Gentoo (what I run) recently patched it, the reason the bug is
fresh in my mind as I saw it in a gentoo konsole package changelog entry
dated June 19th.
There's a couple workarounds available while you're waiting for the patch
to hit your distro:
One is to arrange for the konsole size to be something other than the
default 80x40 when it starts. You can do this by either checking that
the save window size and position checkbox found on the general tab of
the profile settings is checked, and resizing to something than the
default 80x40 chars size, then quitting, or by using kwin's window rules
(what I had done, the reason I never noticed the bug here).
The other is a bit more technical. In your ~/.bashrc, script a SIGWINCH
sent to the bash process as it starts up. This should cause it to check
its window size and set the $LINES and $COLUMNS variables (which is what
is set incorrectly that the ncurses programs are using) appropriately. A
commandline such as the following (untested) should do it, without
causing any harm in a VC (outside of X). (kill doesn't actually kill
anything in this case, but rather sends the signal it's given on the
commandline, #28, the sigwinch signal, instead of the default #15,
sigterm, which /would/ normally cause a termination/kill. $$ is bash
notation for its own PID, so the effect is that bash sends itself the
sigwinch signal, triggering the desired recalculation.)
kill -28 $$
That's untested, obviously as I never had the problem to test it on and
didn't even know about the problem until I read the gentoo changelog
entry, but I believe it should work. You can just use the window resize
and save trick instead, if you don't do enough shell scripting to
understand the line and/or are uncomfortable with it (or if it doesn't
work, for some reason).
