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

KdePim/Kontact was running. Rekonq was started out of Kmail to open a link on www.westfalia.de. After switching to another site of westfalia.de (http://www1.westfalia.de/shops/technik/beleuchtung/leuchten/taschenlampen/530701-36_led_akku_scheinwerfer_dc_9_14v300ma_ladezeit_10_14_stunden.htm?refKey=NJLK1zadd) rekonq freezes and crashed.

-- Backtrace:
