Description Dirk Heinrichs 2012-12-31 16:43:32 UTC

As the summary says: When I try to load https://bugs.kde.org in konqueror with webkit enabled, it doesn't load. The page stays blank forever. It works fine in khtml, though.

It also crashes when loading a page from sourceforge.net.

KDE version is 4.10 RC1, kpart-webkit version is 1.3~git20120518.9a111005-2.

Reproducible: Always

Steps to Reproduce:
1. Load either https://bugs.kde.org (blank page) or http://www.sourceforge.net (crash) while webkit is enabled in konqueror.
Actual Results:  
Get a blank page or even see konqueror crash.

Expected Results:  
Load the bugzilla page/don't see a crash.

Could not reporoduce. I writing this response using Konqueror + kwebkitpart from git.

Comment 2 Dirk Heinrichs 2012-12-31 19:21:54 UTC

Hmm, now that I have switched back from khtml to webkit, I also cant reproduce it anymore. However, I can still reproduce the sf.net crash.

I am almost certain that is an upstream issue. There were a lot of sites that used to cause a crash (mainly due to an SVG bug) when I was using the stock QtWebKit 2.2 release. However, once I switched to the compiling qtwebkit 2.3 branch from git, I see none of those crashes. I know at least the SVG bug that caused a lot of crashes for me is fixed in that branch. See https://bugs.webkit.org/show_bug.cgi?id=97258.

Anyhow, can you please post the backtrace from the crash to confirm that it is an upstream issue as I suspect.

Backtrace for the sf.net crash

Attached the backtrace for the sf.net crash. Hope it's useful (drkonqi rated it with 2 stars).

Comment 5 Dawit Alemayehu 2013-01-19 16:26:00 UTC

Based on the backtrace you sent, this is not caused by the SVG bug I mentioned in comment #3. Unfortunately, I still cannot reporduce this crash by going to sf.net.

Comment 6 Dawit Alemayehu 2013-01-21 17:40:54 UTC

This should be reported upstream to QtWebKit bug database [1] if the crash is not resolved by the upcoming QtWebKit-2.3 release [2].
