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?
Could you try "helgrind" as a tool? What you see is most likely a crash in an other thread.
I usually work my way through all tools that in valgrind, beginning with memcheck (the default), then helgring, callgrind ... simply down the list http://www.valgrind.org/docs/manual/manual.html - and I do not use virtualbox for debugging (but I don't know if it matters).
