Comment 1 Will Stephenson 2011-02-08 20:27:55 UTC 
Dawit, is there a better bugzilla component for kwebkit stuff?
Comment 2 Dawit Alemayehu 2011-02-09 22:34:07 UTC 
(In reply to comment #1)
> Dawit, is there a better bugzilla component for kwebkit stuff?

No. This is the correct component for this report since it involves a crash in a class that is part of kdelibs/kdewebkit. If the issue was kwebkitpart specific then there is "kwebkitpart/general".

More importantly though the code that fills forms has been scrapped and reimplemented for KDE 4.6.1 and up because of bug in QWebElement that prevents proper form filling when forms are laid out a certain way. IOW, the place where the back trace shows the crash occurred is no more in both KDE/master and KDE/4.6 branches.

Is there anyone you can try one of those versions ? For the record, just going to the link you provided does not cause a crash here with the KDE/master.
Comment 3 Will Stephenson 2011-02-09 23:09:36 UTC 
Yes, I can test 4.6 branch tomorrow.
Comment 4 Dawit Alemayehu 2011-02-28 07:51:43 UTC 
Will, can this bug report be closed or do you still experience similar crashes ?
Comment 5 Dawit Alemayehu 2011-04-21 06:17:38 UTC 
Closing as being fixed. Please reopen the ticket if the problem persists in KDE 4.6.1 and up.
