Comment 4 Andrea Diamantini 2012-01-24 10:15:23 UTC 
Can you please check this with:
rekonq 0.8.1
qtwebkit 2.2.x
kdelibs 4.7.x

I just have a couple of people finding this fixed upstream in this situation.
Comment 5 Martin 2012-01-29 11:56:00 UTC 
At the moment I still (again?) have the bug. I am using
rekonq 0.8.72
qtwebkit 2.2.1
kdelibs 4.8.0

It is enough to visit the youtube main page to get a crash. This works every time.

New crash information added by DrKonqi

rekonq (0.8.72) on KDE Platform 4.8.00 (4.8.0 using Qt 4.8.0

This is a recent backtrace, even though Dr. Konqi complains that I do not have all debug symbols installed (I just tried to install them before but the needed packages could not be found). I hope that helps.

Comment 7 Andrea Diamantini 2012-01-29 21:24:40 UTC 
If it crashed on youtube, the PluginView code crashing you see in the backtrace crashes surely cause of flash. What's your flash version?
Comment 8 Martin 2012-01-30 17:33:53 UTC 
My flash version is 11.1.102.55.

Somehow it always comes down to flash not working properly...

No, I'm sorry. This is another upstream bug.

Comment 10 Martin 2012-05-25 08:38:06 UTC 
Since some time I haven't experienced this bug. Could be that it is already resolved. Using rekonq 0.9.1 with KDE 4.8.3 and Flash 11.2.202.235. I will close it for now.
