Bug 323266

Application: konqueror (4.10.5 "release 1")
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.1.10-1.29-default i686
Distribution: "openSUSE 12.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I was googling for "chrome vs netscape" and then went to the first website mentioned in the results. On that page, there was a large Netscape logo which had a link directly below it. I scrolled the page down to where it showed the "Ratings Breakdown" and then scrolled back up to where the Netscape logo was. When I clicked that link under the logo, Konqueror crashed.

To see if Konqueror would crash like that again, I started Konqueror a few times and tried those steps. Konqueror crashed about two of those times and the third time it didn't crash. Every time after that it also didn't crash.
This page has the link that I clicked: http://web-browsers.findthebest.com/compare/3-31/Chrome-vs-Netscape

The crash can be reproduced sometimes.

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