Description idoitprone 2011-04-16 16:19:43 UTC

Application: konqueror (4.6.2 (4.6.2) "release 3")
KDE Platform Version: 4.6.2 (4.6.2) "release 3"
Qt Version: 4.7.2
Operating System: Linux 2.6.38.2-19-desktop i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
I been noticeting the behavior for awhile now and other crashes I cannot reproduce. Right now I just feel like reporting it, since it said on the backtrace "Information may be useful," and also it happen to me again from last night. The problem lies in Facebook new image viewer. http://www.facebook.com/notes/facebook-engineering/developing-facebooks-new-photo-viewer/499447633919 According to those notes, they said the photoviewer uses less javascript and more css. I am not a developer, I am trying to give as much information. By the way, I am using webkit for konqueror. Thank you for all your support. I noticed that konqueror is getting better. I can use gmail now, lol.

Step to reproduce
1. open up konqueror
2. go to facebook
3. click on an album that has 2 or more photos
4. click on the photo to change photos until it crashes. 5-10 photos quickly

The crash can be reproduced some of the time.

Comment 1 Dawit Alemayehu 2011-04-16 19:52:00 UTC

I am unable to reproduce the problem as described using Qt 4.7.2 with the latest development version of QtWebKit and kwebkitpart. And since the backtrace shows, the crash happening so far up high in the QtWebKit stack, I am inclined to think this is an upstream problem. As such this issue needs to be reported upstream:

http://trac.webkit.org/wiki/QtWebKitBugs

Comment 2 idoitprone 2011-04-16 22:28:06 UTC

Wow, quick response. It not simple to reproduced this bug. It happens from time to time. I not even sure this crash happens with other browsers. I just reported it since it said the information is useful or whatever. Thank you for response.

Comment 3 idoitprone 2011-04-16 22:39:57 UTC

Wow, quick response. This crash is not easy to reproduce. It just happens from time to time. I was little inclined not to report it, but since the back-trace say it information may be useful. I might as well report it. I have never notice this behavior on other browsers such as chromium. Thank you for your input. So I guess I have to report it upstream?
