Comment 1 Andrea Diamantini 2012-08-20 15:28:45 UTC 
What about with rekonq 1.0 and latest qt 4.8.x?
Comment 2 skumara2000 2012-08-21 01:53:41 UTC 
I'm using ppa:kubuntu/kubuntu-backports and have updated to the latest version on kde files. There are only rekonq 0.9.1 in repository. How to get rekonq 1.0?
Comment 3 Andrea Diamantini 2012-08-21 14:51:07 UTC 
no idea, sorry. You should ask in kubuntu IRC channel, I guess...
Comment 4 Andrea Diamantini 2012-09-19 16:31:12 UTC 
QtWebkit crash, probably solved in the 2.2.x series (cannot reproduce here). Please upgrade to last qtwebkit release and test this again. If happens with the same backtrace, report it here: http://webkit.org/new-qtwebkit-bug
