Those comments were written back in the KDE 3 days and I believe do not refer
to a leak but just that if you set the number of scrollback lines to a very
large number, open many tabs and fill all those buffers then a lot of memory
will be used - see my calculations above.

I need to confirm that there is actually a leak first - not just a lot of
memory being used as a result of many tabs and a large scrollback buffer in
each.  I valgrinded a simple Konsole session with 1K scrollback opening tabs,
filling the scrollback buffer and then closing the tab but did not see any
relevant problems in the leak report.

It would be helpful if you could try as well using:

valgrind --leak-check=full --show-reachable=yes konsole --nofork
