Bug 319684

Application: rekonq (2.2.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-19-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
The Verge web site starts to load reader comments when the page is scrolled down so that the comments section becomes visible. Rekonq crashes as soon as the comments start downloading. It is reproducible on all article pages I have visited on The Verge.
- Custom settings of the application:
The Verge was the only web site open when Rekonq crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
