New crash information added by DrKonqi

konqueror (4.5.2 (KDE 4.5.2)) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.7.0

- What I was doing when the application crashed:

I visited <http://scienceblogs.com/pharyngula/2006/09/cats_candy_and_evolution.php> followed by <http://scienceblogs.com/pharyngula/2006/09/no_friday_cat_blogging_for_us.php>. It is not very reproducible (in fifty tries it happened twice: yes, I am too obsessive: by the look of frame 81 this is because the crash happened rendering some of the dynamic 'see this other scienceblogs site' stuff that SB puts on every page), but is plainly a wild or (more likely) stale pointer somewhere, pointing indirectly into the void *.
