Bug 333633

Application: rekonq (2.4.2)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I visited ebay.com/motors. I selected "Citroen" from brand menu under "Find a car or truck".  I pressed the "Search Cars & Trucks" button.  Then rekonq crashed.  It happened every time I tried this.

If this turns out to be a Webkit bug, would the rekonq developers please, please fix it.  Rekonq has been unstable like this for well over a year.  With the release of Kubuntu 14.04, I hoped that rekonq would be good enough to be my everyday browser.  You have no idea how sad it makes me to use Firefox instead of rekonq.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
