I used valgrind-2.2.0.manual.tar.bz2, but I also don't think it matters.

I enabled the KDir* debug outputs. If you need more, let me know.
The steps to reproduce were:
- open the directory where valgrind-2.2.0-manual.tar.bz2 is
- enter the archive, the "manual" dir in the archive and click on an 
HTML file
- press the up button 3 times. Should crash on the 3rd press, when you 
exit the archive.
