Note to Dario: I suspect this one is a dup of #186949.
can't reproduce... could you try to svn up? I commited a symptomatic fix for a crash that looks like this one yesterday.
Here using: Qt: 4.5.0 + qt-copy-patches-936035 KDE: 4.2.68 (KDE 4.2.68 (KDE 4.3 >= 20090327)) kdelibs svn rev. 946159 / kdebase svn rev. 946160 on ArchLinux i686 - Kernel 2.6.28.7 I can't reproduce the crash even when using the Raster graphicssystem @Christophe: I'm going to take a look at it. Thanks
The only connection I saw was: "khtml::RenderLayer::paintLayer" and may be the QPainter/QPaintEngine functions at the top. But bug 186949 sounds like it's crashing everytime (or may be it has the offending site as home... ), and this is related to a site. There are no other reports with "QPaintEngine::hasFeature" or "khtml::BufferedPainter::transfer" on it.
Thanks for the tips. I can't reproduce the crash with Khtml from trunk (except if I try to compile it with GCC 4.4 but that's another issue :)). Closing.
