This crash is in QtWebKit and we usually request that a ticket be opened upstream. However, I am currently using the upcoming release of QtWebKit 2.0 (more recent version than the one you are using) and I cannot duplicate this crash. That website works fine here with the recent version. As such please feel free to reopen this ticket if you can duplicate the bug once QtWebKit 2.0 comes out probably sometime in May. Thanks for the report. Created attachment 49506 [details]
New crash information added by DrKonqi
konqueror (4.5.60 (KDE 4.5.60 (KDE 4.6 >= 20100627))) on KDE Platform 4.5.61 (KDE 4.5.61 (KDE 4.6 >= 20100724)) using Qt 4.8.0
- What I was doing when the application crashed:
Going to lots of websites with pictures, in general, crash frequently. I also crash when I go to the link supplied by the bug this one is attached to.

Again as the original backtrace clearly shows, the crash seems to occur in Qt's font handling classes which is an upstream issue. The second backtrace is useless because it is missing critical information such as platform (read: distribution) and the actual point where the crash occurs. IOW, the whole backtrace needs to be posted. Anyhow reopening this ticket will not get the issue fixed upstream for you guys since I do not have the time to track issues that far up the chain and still cannot reproduce this bug on Arch Linux, the latest KDE 4.5 branch and QtWebKit 2.0. My suggestion is for one of you to try and reproduce the bug with Arora, a Qt only based browser, to see if the issue is KDE specific...

I used the kde automatic bug reporter and I thought it would submit distribution as well as my complete backtrace. I will look at upstream qt and see if this bug is known over there. Thanks for your time. Could also simply be a freetype bug in FT_Get_PS_Font_Info(). It works here using both Konqueror in KHTML mode as well as in KWebKit mode, using freetype 2.3.12 and Qt from 4.7 branch. Which freetype version do you use? There was some change around 2.3.8/2.3.9 time that could cause memory corruption in said function. |
