Comment 1 Dawit Alemayehu 2013-01-19 16:41:17 UTC 
The backtrace seems to indicate that this is an upstream QtWebKit issue. Can you reliably reproduce the crash ?
Comment 2 kavol 2013-01-19 20:05:08 UTC

unfortunately not ...

New crash information added by DrKonqi

konqueror (4.9.5) on KDE Platform 4.9.5 using Qt 4.8.4

- What I was doing when the application crashed:

I've accidentaly hit some wrong keyboard shortcut - I think it was left alt + right arrow or something like that (I'm not sure, I grabbed the modifier with my left hand without looking - it may have even been left windows key - and touched something accidentally while moving my right hand towards the "m" key I wanted to hit ...)

Konqueror crashed right after that ... and it was while viewing the same site like the last time - abclinuxu.cz
