Bug 335957

Application: konqueror (4.8.5 (4.8.5))
KDE Platform Version: 4.8.5 (4.8.5) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-64-generic x86_64
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:  following links from Google news using Konqueror.

- Unusual behavior I noticed:  Selected news item in Google news, navigated to non-google website in new Konqueror tab, while non-Google webpage loads Konqueror crashes with "segmentation fault" notification.  Exact same behavior yesterday using reconq browser, so may be khtml related.

- Custom settings of the application:  Using unmodified default settings.  (However, GNOME Color Chooser presets control personalized appearance of KDE applications like Konqueror and reconq.)

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
