That ht is zero here seems bogus, but I can not explain this.  But maybe the
whole backtraceis bogus, and the real problem is another one.  I have fixed
some bugs in the scrolling calculation in libcons, can you try it out if
that fixes things for you?

Note that you must the new version of the console server, too.

Do you still see this with the new version?  I have fixed a couple of bugs,
and the other bug I told you about, the artifacts in "lynx
www.slashdot.org", is now mostly gone.  What is still corrupt is probably
due to the · (bullet) displayed by lynx is not correctly displayed by
ncurses.  I have not looked further into this yet.

I don't see any display bugs in my VGA client anymore, but it doesn't have a
lot of testing yet.

Roland suggested C-\, what do you think of that?  Probably depends on the
keyboard layout.
