Completely unrelated to bug 305864 though it seems like it simply because they share similar backtrace that goes through kwebkitpart. 

However, this bug is completely different, not to mention reproducible, and fixed for KDE 4.9.2 by sheer coincedence (because I ran into it myself when working on something else).
