Description Алексей Шилин 2012-08-31 18:17:25 UTC

I was reading http://unixforum.org/index.php?showtopic=132768 using Konqueror 4.9 with WebKit KPart and right-clicked the scrollbar inside the second "code" block of the first post (where Xorg.0.log contents is pasted). The browser crashed immediately after that.
Same happens at http://translate.yandex.ru/ if you insert enough text for scrollbars to appear.

Reproducible: Always

Steps to Reproduce:
1. Launch Konqueror with WebKit KPart as a default one.
2. Go to http://unixforum.org/index.php?showtopic=132768 .
3. Right-click the scrollbar inside the second "code" block of the first post.
Actual Results:  
Konqueror crashed.

Expected Results:  
Konqueror should have shown a usual scrollbar context popup menu.

Konqueror with KHTML KPart works, so does Rekonq. Therefore it seems to be not a Konqueror or QtWebKit problem.
kpart-webkit version: 1.3~git20120518.9a111005-2 as currently in Debian testing/unstable and Kubuntu quantal.
Fedora 17 uses 1.2-0.3.20111030 and is affected too.
