OK,

  What tool in valgrind is the one we want? I tried cachegrind and that didn't
produce anything:

08:09 valkyrie:~> valgrind --tool=cachegrind kwrite
==1042== Cachegrind, a cache and branch-prediction profiler
==1042== Copyright (C) 2002-2011, and GNU GPL'd, by Nicholas Nethercote et al.
==1042== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info
==1042== Command: kwrite
==1042==
Killed

  The strange thing was I could open long files in kwrite and cursor down
without a crash when running in valgrind. However, pasting until the line
wrapped caused the crash as normal. Let me know what the valgrind command line
should look like. Or, is trying to run valgrind in virtualbox not going to work
to begin with?
