--- Comment #6 from Dawit Alemayehu <adawit@kde.org> ---
Ok. Now I can reproduce the crash. Unfortunately, I am not yet able to
determine what the actually cause is just yet, but it is in kdelibs and not
Konqueror. Anyhow, I also was not able to reproduce the crash when running
Konqueror through valgrind. Here is a better backtrace:

Application: Konqueror (konqueror), signal: Segmentation fault
