Bug 275128

Application: konqueror (4.6.3 (4.6.3))
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1-amd64 x86_64
Distribution (Platform): Debian unstable

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

Click "Next Page" on http://deviantart.com after a research. Maybe 10 tabs open. Often crash with the same action on the same website. I use WebKit instead of KHTML. No crash of another apps.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
